A Tree is a data model representing a set of objects linked into a hierarchy.
A Tree has no visual presentation, it is displayed by a TreeGrid or ColumnTree when supplied as TreeGrid.data or ColumnTree.data.
A Tree can be constructed out of a List of objects interlinked by IDs or via explicitly specified Arrays of child objects. See modelType for an explanation of how to pass data to a Tree.
Typical usage is to call TreeGrid.fetchData() to cause automatic creation of a ResultTree, which is a type of Tree that automatically handles loading data on demand. For information on DataBinding Trees, see TreeDataBinding.

```
    For a multi-link tree, indicates whether client-side filtering is allowed on the fields of the linkDataSource. When this property is true, filtering operations involving link fields work as expected (ie, as if those fields were present on the main dataSource); when this value is not true, criterions involving link fields are simply ignored.
    Note, setting this property true causes filtering operations to perform an additional record duplication per node in the dataset to be filtered. This adds some overhead, so you should consider likely data volumes before enabling it (though in fact, client-side filtering of trees is relatively expensive anyway, so acceptable use cases probably already involve quite low data volumes)
    This property has no effect for regular, non-multiLink trees.
    
    Parameters:
    
    allowFilterOnLinkFields - New allowFilterOnLinkFields value. Default value is null
    
    Returns:

  - setOpenProperty
```
public Tree setOpenProperty(java.lang.String openProperty)
```
    The property consulted by the default implementation of isOpen() to determine if the node is open or not. By default, this property is auto-generated for you, but you can set it to a custom value if you want to declaratively specify this state, but be careful - if you display this Tree in multiple TreeGrids at the same time, the open state will not be tracked independently - see SharingNodes for more info on this.
    For multi-link trees, we do not track open state on the nodes themselves, because this would mean that multiple instances of a node in the tree would open and close in lockstep. Instead, open state is tracked in an internal index structure, and the openProperty is not used at all.
    Note : This is an advanced setting
    
    Parameters:
    
    openProperty - New openProperty value. Default value is null
    
    Returns:

```
public Tree setParentIdField(java.lang.String parentIdField)
                      throws java.lang.IllegalStateException
```
    For trees with modelType "parent", this property specifies the name of the property that contains the unique parent ID of a node. Default value is "parentId". See TreeNode.parentId for usage.
    Note : This is an advanced setting
    
    Parameters:

  - setPathDelim
```
public Tree setPathDelim(java.lang.String pathDelim)
```
    Specifies the delimiter between node names. The pathDelim is used to construct a unique path to each node. A path can be obtained for any node by calling getPath() and can be used to find any node in the tree by calling find(). Note that you can also hand-construct a path - in other words you are not required to call getPath() in order to later use find() to retrieve it.
    
    The pathDelim can be any character or sequence of characters, but must be a unique string with respect to the text that can appear in the nameProperty that's used for naming the nodes. So for example, if you have the following tree:
```
  one
    two
      three/four
  
```
    Then you will be unable to find the three/four node using find() if your tree is using the default pathDelim of /. In such a case, you can use a different pathDelim for the tree. For example if you used | for the path delim, then you can find the three/four node in the tree above by calling tree.find("one|two|three/four").
    
    The pathDelim is used only by getPath() and find() and does not affect any aspect of the tree structure or other forms of tree navigation (such as via getChildren()).
    Note : This is an advanced setting
    Parameters:
    
    pathDelim - New pathDelim value. Default value is "/"
    
    Returns:
    
    Tree instance, for chaining setter calls

```
public Tree setReportCollisions(java.lang.Boolean reportCollisions)
                         throws java.lang.IllegalStateException
```
    If new nodes are added to a tree with modelType:"parent" which have the same id field value as existing nodes, the existing nodes are removed when the new nodes are added.
    If reportCollisions is true, the Tree will log a warning in the developer console about this.
    Note that if an id collision occurs between a new node and its ancestor, the ancestor will be removed and the new node will not be added to the tree.
    
    Parameters:
    
    reportCollisions - New reportCollisions value. Default value is true
    
    Returns:

  - setRoot
```
public Tree setRoot(TreeNode root)
```
    If you're using the "parent" modelType, you can provide the root node configuration via this property. If you don't provide it, one will be auto-created for you with an empty name. Read on for a description of what omitting the name property on the root node means for path derivation.
    If you're using the "children" modelType, you can provide the initial tree data via this property. So, for example, to construct the following tree:
```
  foo
    bar
  zoo
  
```
    You would initialize the tree as follows:
```
  Tree tree = new Tree();
  tree.setRoot(
      new TreeNode("root",
          new TreeNode("foo",
              new TreeNode("bar")),
          new TreeNode("zoo")
      )
  );
  
```
    Note: if you initialize a Tree with no root value, a root node will be auto-created for you. You can then call add() to construct the tree.
    
    If this method is called after the component has been drawn/initialized: Set the root node of the tree. Called automatically on this Tree during initialization and on the Tree returned from a call to duplicate().
    Parameters:
    
    root - new root node. Default value is null

      )
  );
  
```
    Note: if you initialize a Tree with no root value, a root node will be auto-created for you. You can then call add() to construct the tree.

  - getChildrenResultSet
```
public ResultSet getChildrenResultSet(TreeNode node)
```
    Returns a ResultSet that provides access to any partially-loaded children of a node. If the node is a leaf, this method returns null.
    
    Parameters:
    
    node - The node whose children you want to fetch.
    
    Returns:
    
    List of children for the node, including an empty ResultSet if the node has no children. For a leaf, returns null.

  - getDescendantNodeLocators
```
public TreeNode[] getDescendantNodeLocators()
```
    Returns a list of link{type:NodeLocator)s identifying all descendants of a node (identified by the parameter NodeLocator). This method is the equivalent of getDescendants(), but for multi-link trees. The list of descendant nodes returned from both methods is identical - a node's descendants are the same regardless of where or how many times that node appears in the tree - but the NodeLocators returned by this method provide additional context that allows you to determine particular occurences of descendant nodes. This is necessary for some use cases - for example, when trying to determine if a particular node occurence is open, or selected.
    
    Returns:
    
    List of descendants of the node.
  - getDescendantNodeLocators
```
public TreeNode[] getDescendantNodeLocators(TreeNode node)
```
    Returns a list of link{type:NodeLocator)s identifying all descendants of a node (identified by the parameter NodeLocator). This method is the equivalent of getDescendants(), but for multi-link trees. The list of descendant nodes returned from both methods is identical - a node's descendants are the same regardless of where or how many times that node appears in the tree - but the NodeLocators returned by this method provide additional context that allows you to determine particular occurences of descendant nodes. This is necessary for some use cases - for example, when trying to determine if a particular node occurence is open, or selected.
    
    Parameters:
    
    node - node in question (root node is assumed if none is specified)
    
    Returns:
    
    List of descendants of the node.
  - getLength
```
public int getLength()
```
    Returns the number of items in the current open list.
    
    Overrides:
    
    getLength in class RecordList
    
    Returns:
    
    number of items in open list
    
    See Also:
    
    getOpenList(com.smartgwt.client.widgets.tree.TreeNode)
  - getLevel
```
public int getLevel(TreeNode node)
```
    Return the number of levels deep this node is in the tree. For example, for this tree:
```
  root
    foo
      bar
  
```
    Calling tree.getLevel(bar) will return 2.
    Note showRoot defaults to false so that multiple nodes can be shown at top level. In this case, the top-level nodes still have root as a parent, so have level 1, even though they have no visible parents.
    For multi-link trees, passing a TreeNode to this method will return the level of one of that node's occurences; it is not predictable which occurence will be used. For multi-link trees, therefore, you should pass a NodeLocator with a path that unambiguously identifies the node occurence you are interested in
    Parameters:
    
    node - node in question, or a suitable NodeLocator
    
    Returns:
    
    number of parents the node has
  - getLevel
```
public int getLevel(NodeLocator node)
```
    Return the number of levels deep this node is in the tree. For example, for this tree:
```
  root
    foo
      bar
  
```
    Calling tree.getLevel(bar) will return 2.
    Note showRoot defaults to false so that multiple nodes can be shown at top level. In this case, the top-level nodes still have root as a parent, so have level 1, even though they have no visible parents.
    For multi-link trees, passing a TreeNode to this method will return the level of one of that node's occurences; it is not predictable which occurence will be used. For multi-link trees, therefore, you should pass a NodeLocator with a path that unambiguously identifies the node occurence you are interested in
    Parameters:
    
    node - node in question, or a suitable NodeLocator
    
    Returns:
    
    number of parents the node has
  - getLoadState
```
public LoadState getLoadState(TreeNode node)
```
    What is the loadState of a given folder?
    
    Parameters:
    
    node - folder in question
    
    Returns:
    
    state of the node
  - getMultiLinkParents
```
public TreeNode[] getMultiLinkParents(TreeNode node)
```
    For multiLink trees, returns the array of this node's direct parents (the actual node objects, not the IDs). For non-multiLink trees, returns an array containing the single parent of this node. See also getParentsAndPositions().
    
    Parameters:
    
    node - node in question
    
    Returns:
    
    the parents of this node
  - getName
```
public java.lang.String getName(TreeNode node)
```
    Get the 'name' of a node. This is node[nameProperty]. If that value has not been set on the node, the node's 'ID' value will be tried (this is node[idField]). If that value is not present on the node, a unique value (within this parent) will be auto-generated and returned.
    
    Parameters:
    
    node - node in question, or a suitable NodeLocator
    
    Returns:
    
    name of the node
  - getName
```
public java.lang.String getName(NodeLocator node)
```
    Get the 'name' of a node. This is node[nameProperty]. If that value has not been set on the node, the node's 'ID' value will be tried (this is node[idField]). If that value is not present on the node, a unique value (within this parent) will be auto-generated and returned.
    
    Parameters:
    
    node - node in question, or a suitable NodeLocator
    
    Returns:
    
    name of the node
  - getNodeLocator
```
public NodeLocator getNodeLocator(java.lang.Integer recordIndex)
```
    For a multi-link tree, this method returns the nodeLocator associated with the particular occurence of the node at the specified index within the current open list of nodes in the tree. Not applicable to non-multilink trees (always returns null)
    
    Parameters:
    
    recordIndex - position of a node occurence within the open list of the tree
    
    Returns:
    
    NodeLocator unambiguously identifying the specific node occurence
  - getParentPath
```
public java.lang.String getParentPath(TreeNode node)
```
    Given a node, return the path to its parent. This works just like getPath() except the node itself is not reported as part of the path.
    
    Parameters:
    
    node - node in question
    
    Returns:
    
    path to the node's parent
    
    See Also:
    
    getPath(com.smartgwt.client.widgets.tree.TreeNode)
  - getParentsAndPositions
```
public Record[] getParentsAndPositions(TreeNode node)
```
    For multiLink trees, returns the array of this node's direct parents and the node's position within each parent. Each entry is a record like this:
```
  [
      {parent: [reference-to-parent-node], position: [this-node's-position-within-the-parent]},
      {parent: [reference-to-parent-node], position: [this-node's-position-within-the-parent]}
  ]
  
```
    For non-multiLink trees, returns null (calling this method makes no sense for non-multiLink trees).
    Parameters:
    
    node - node in question
    
    Returns:
    
    the parents and positions of this node
  - getPath
```
public java.lang.String getPath(TreeNode node)
```
    Returns the path of a node - a path has the following format: ([name][pathDelim]?)*
    
    For example, in this tree:
```
  root
    foo
      bar
  
```
    Assuming that pathDelim is the default /, the bar node would have the path root/foo/bar and the path for the foo node would be root/foo.
    
    Once you have a path to a node, you can call find(path) to retrieve a reference to the node later.
    Note: Nodes in multi-link trees do not have a single path, because a given node can occur in multiple places in the tree. Therefore, if you pass a TreeNode instance to this method, it returns the path to one occurence of the node; which particular occurence it chooses is not predictable, and there may be other paths to other occurences of the same node in the tree. The only way to obtain an unambiguous path for a particular occurence of a node is to call getPathForOpenListIndex(), passing in the position of the node occurence in the tree's openList (which will be the same as the record number of the node's visual occurence in a treeGrid); if the node occurence is not yet in the tree's openList - either because its parent has not yet been opened, or because the tree is in the process of being built - the tree is not able to provide a path to the node occurence. In this case, you would have to obtain the path in application code, by reference to the original data and linkData
    Parameters:
    
    node - node in question
    
    Returns:
    
    path to the node
    
    See Also:
    
    getParentPath(com.smartgwt.client.widgets.tree.TreeNode)
  - getPathForOpenListIndex
```
public java.lang.String getPathForOpenListIndex(java.lang.Integer recordIndex)
```
    This method returns the path to the node at the specified index within the current open list of nodes in this tree. Note that for a node that appears in more than one place in a multi-link tree, the returned path will be the visible path to the node in the specified index.
    See getPath() for more information on paths for TreeNodes.
    
    Parameters:
    
    recordIndex - position of a node within the open list of the tree
    
    Returns:
    
    path to the node
  - getTitle
```
public java.lang.String getTitle(TreeNode node)
```
    Return the title of a node -- the name as it should be presented to the user. This method works as follows:
    - If a titleProperty is set on the node, the value of that property is returned.
    - Otherwise, if the nameProperty is set on the node, that value is returned, minus any trailing pathDelim.
    - Finally, if none of the above yielded a title, the value of defaultNodeTitle is returned.
    You can override this method to return the title of your choice for a given node.
    
    To override the title for an auto-constructed tree (for example, in a databound TreeGrid), override TreeGrid.getNodeTitle() instead.
    Parameters:
    
    node - node for which the title is being requested
    
    Returns:
    
    title to display
    
    See Also:
    
    TreeGrid.getNodeTitle(com.smartgwt.client.data.Record, int, com.smartgwt.client.widgets.grid.ListGridField)
  - hasChildren
```
public java.lang.Boolean hasChildren(TreeNode node)
```
    Returns true if this node has any children.
    
    Parameters:
    
    node - node in question
    
    Returns:
    
    true if the node has children
  - hasFolders
```
public java.lang.Boolean hasFolders(TreeNode node)
```
    Return true if this this node has any children that are folders.
    
    Parameters:
    
    node - node in question
    
    Returns:
    
    true if the node has children that are folders
  - hasLeaves
```
public java.lang.Boolean hasLeaves(TreeNode node)
```
    Return whether this node has any children that are leaves.
    
    Parameters:
    
    node - node in question
    
    Returns:
    
    true if the node has children that are leaves
  - isDescendantOf
```
public java.lang.Boolean isDescendantOf(TreeNode child,
                                        TreeNode parent)
```
    Is one node a descendant of the other?
    
    Parameters:
    
    child - child node
    
    parent - parent node
    
    Returns:
    
    true == parent is an ancestor of child
  - isFolder
```
public java.lang.Boolean isFolder(TreeNode node)
```
    Determines whether a particular node is a folder. The logic works as follows:
    - If the TreeNode has a value for the isFolderProperty (TreeNode.isFolder by default) that value is returned.
    - Next, the existence of the childrenProperty (by default TreeNode.children) is checked on the TreeNode. If the node has the children property defined (regardless of whether it actually has any children), then isFolder() returns true for that node.
    Parameters:
    
    node - node in question
    
    Returns:
    
    true if the node is a folder
  - isInAncestorChain
```
public void isInAncestorChain()
```
    Returns true if the passed-in node ID is already present in the parent's ancestor chain. This means that either the parent node itself, or its parent, grandparent, and so on, has the same ID as the one passed in. This method is used when linking new nodes into a tree, to ensure that we don't link in nodes that will lead to circular references by virtue of a node being its own parent (or its own child, depending which way round you prefer to think of it)
    Note that multi-link trees potentially have more than one ancestor chain for any given node, so this method returns true if the parameter ID is used by any node in any of the parent's ancestor chains.
  - isLeaf
```
public java.lang.Boolean isLeaf(TreeNode node)
```
    Returns true if the passed in node is a leaf.
    
    Parameters:
    
    node - node in question
    
    Returns:
    
    true if the node is a leaf
    
    See Also:

    Returns:
    
    folder is loaded or is currently loading
  - isMultiLinkTree
```
public void isMultiLinkTree()
```
    Returns true if this is a multi-link tree - ie, one that can contain the same node in more than one place. Otherwise, returns false.
    See linkData and ResultTree.linkDataSource for further details of multiLink trees.
  - isOpen
```
public java.lang.Boolean isOpen(TreeNode node)
```
    Whether a particular node is open or closed (works for leaves and folders). Note, for multi-link trees, passing a NodeLocator is the only unambiguous way to specify the node.
    
    Parameters:
    
    node - the node in question, or the the node's ID, or a NodeLocator object
    
    Returns:
    
    true if the node is open
  - isOpen
```
public java.lang.Boolean isOpen(java.lang.String node)
```
    Whether a particular node is open or closed (works for leaves and folders). Note, for multi-link trees, passing a NodeLocator is the only unambiguous way to specify the node.
    
    Parameters:
    
    node - the node in question, or the the node's ID, or a NodeLocator object
    
    Returns:
    
    true if the node is open
  - isOpen
```
public java.lang.Boolean isOpen(java.lang.Integer node)
```
    Whether a particular node is open or closed (works for leaves and folders). Note, for multi-link trees, passing a NodeLocator is the only unambiguous way to specify the node.
    
    Parameters:
    
    node - the node in question, or the the node's ID, or a NodeLocator object
    
    Returns:
    
    true if the node is open
  - isOpen
```
public java.lang.Boolean isOpen(NodeLocator node)
```
    Whether a particular node is open or closed (works for leaves and folders). Note, for multi-link trees, passing a NodeLocator is the only unambiguous way to specify the node.
    
    Parameters:
    
    node - the node in question, or the the node's ID, or a NodeLocator object
    
    Returns:
    
    true if the node is open
  - isParent
```
public java.lang.Boolean isParent(TreeNode node,
                                  TreeNode parent)
```
    Returns true if "parent" is the parent of "node". This is straightforward and definitive for ordinary trees, because nodes can only have one parent. In multiLink trees, however, nodes can have multiple parents, so this method returning true only means that "parent" is a parent of "node" - there may or may not be others.
    
    Parameters:
    
    node - the node in question
    
    parent - the node to query to see if is a parent of the other node
    
    Returns:
    
    true if "parent" is a parent of "node"; otherwise false
  - isRoot
```
public java.lang.Boolean isRoot(TreeNode node)
```
    Return true if the passed node is the root node.
    
    Parameters:
    
    node - node to test
    
    Returns:
    
    true if the node is the root node
  - linkDataChanged
```
public void linkDataChanged()
```
    For multi-link trees only, called when links are added to or removed form the tree.
    
    Note that on a big change (many items being added or deleted) this may be called multiple times
  - loadChildren
```
public void loadChildren(TreeNode node)
```
    Load the children of a given node.
    For a databound tree this will trigger a fetch against the Tree's DataSource.
    
    Parameters:
    
    node - node in question

```
    Removes a node, along with all its children. See "Modifying ResultTrees" when working with a ResultTree for limitations. Note, if this is a multi-link tree, you must pass in a NodeLocator rather than a node or id.
    
    Parameters:
    
    node - node to remove, or the node's ID, or a NodeLocator
    
    Returns:
    
    true if the tree was changed as a result of this call

    true if the tree was changed as a result of this call
  - removeChildren
```
public void removeChildren(TreeNode node)
```
    Removes all children of the node and sets it to a loaded state. For non-ResultTrees, or non-paged ResultTrees, add() or addList() can then be used to provide new children. For paged ResultTrees, DataSource.updateCaches() must be used to insert nodes into the cache as local data, since such ResultTrees are considered read-only, and add() and addList() are not perrmitted.
    
    Parameters:
    
    node - folder in question
    
    See Also:
    
    getLoadState(com.smartgwt.client.widgets.tree.TreeNode), reloadChildren(com.smartgwt.client.widgets.tree.TreeNode)
  - setChildren
```
public void setChildren(TreeNode parent,
                        java.util.List newChildren)
```
    Replaces the existing children of a parent node, leaving the node in the loaded state. Only a flat list of children nodes is supported, as in addList().
    
    Parameters:
    
    parent - parent of children
    
    newChildren - children to be set
    
    See Also:
    
    removeChildren(com.smartgwt.client.widgets.tree.TreeNode), DataSource.updateCaches(com.smartgwt.client.data.DSResponse)
  - unloadChildren
```
public void unloadChildren(TreeNode node)
```
    Deprecated. It's recommended that you instead use reloadChildren() to reload the children of a folder, or removeChildren() if you need to clear the cached children of a folder to add specific local data.
    
    Unload the children of a folder, returning the folder to the "unloaded" state.
    
    Parameters:
    
    node - folder in question
  - discoverTree
```
public static void discoverTree(TreeNode[] nodes,
                                DiscoverTreeSettings settings,
                                java.lang.String parentChildrenField)
```
    given a hierarchy of objects with children under mixed names, heuristically discover the property that holds children and copy it to a single, uniform childrenProperty. Label each discovered child with a configurable "typeProperty" set to the value of the property that held the children.
    
    Parameters:
    
    nodes - list of nodes to link into the tree.
    
    settings - configures how the tree will be explored
    
    parentChildrenField -
  - findChildrenProperty
```
public static java.lang.String findChildrenProperty(TreeNode node,
                                                    ChildrenPropertyMode mode)
```
    heuristically find a property that appears to contain child objects. Searches through a node and find a property that is either Array or Object valued.
    
    Parameters:
    
    node - the node to check
    
    mode - determines how to chose the property that appears to contain child objects
    
    Returns:
    
    the name of the property that holds the children
  - setDefaultProperties
```
public static void setDefaultProperties(Tree treeProperties)
```
    Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.
    Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.
    
    Parameters:
    
    treeProperties - properties that should be used as new defaults when instances of this class are created
    
    See Also:
    
    SGWTProperties
  - setData
```
public Tree setData(TreeNode[] nodes)
```
    Optional initial data for the tree. How this data is interpreted depends on this tree's modelType.
    If modelType is "parent", the list that you provide will be passed to linkNodes(com.smartgwt.client.widgets.tree.TreeNode[]), integrating the nodes into the tree.
    In this case the root node must be supplied separately via root. So for example, to create this tree:
```
foo
    bar
        zoo 
```
    with modelType:"parent", you can do this:
```
        TreeNode root = new TreeNode("root");

        Tree tree = new Tree();
        tree.setRoot(root);
        tree.setModelType(TreeModelType.PARENT);

        TreeNode data[] = new TreeNode[3];
        data[0] = new TreeNode("foo");
        data[0].setID("foo");
        data[0].setParentID("root");
        data[1] = new TreeNode("bar");
        data[1].setID("bar");
        data[1].setParentID("foo");
        data[2] = new TreeNode("zoo");
        data[2].setID("zoo");
        data[2].setParentID("bar");
        tree.setData(data);
 
```
    Specifying the root node explicitly allows you to give it a name, changing the way path derivation works (see root for more on naming the root node).
    For modelType:"children" trees, the data passed in will be assumed to be an array of children of the tree's root node.
    Parameters:
    
    nodes - data
    
    Returns:
    
    Tree instance, for chaining setter calls
  - getData
```
public ListGridRecord[] getData()
```
  - setLinkData
```
public void setLinkData(Record[] linkData)
```
    For a multi-link tree, this property specifies the parent-child relationships between the nodes. The nodes themselves are provided in the regular tree data. Note that multi-link trees must specify a modelType of "parent".
    For a regular, non-multiLink tree, linkData is ignored.
    Minimally, the link data should include a node id, parent id and optionally the position of the child within that parent (only required if allowDuplicateChildren is set). To describe this multi-link tree:
```
   foo
     bar
       baz
     zoo
       bar
         baz
 
```
    you would provide node information in the tree's data like this:
```
  TreeNode data[] = new TreeNode[4];
  data[0] = new TreeNode("foo");
  data[0].setID("foo");
  data[1] = new TreeNode("bar");
  data[1].setID("bar");
  data[2] = new TreeNode("baz");
  data[2].setID("baz");
  data[3] = new TreeNode("zoo");
  data[3].setID("zoo");
  tree.setData(data);
 
```
    and link information in linkData like this:
```
  Record linkData[] = new Record[4];
  linkData[0] = new Record();
  linkData[0].setAttribute("id", "bar");
  linkData[0].setAttribute("parentId", "foo");
  linkData[1] = new Record();
  linkData[1].setAttribute("id", "baz");
  linkData[1].setAttribute("parentId", "bar");
  linkData[2] = new Record();
  linkData[2].setAttribute("id", "zoo");
  linkData[2].setAttribute("parentId", "foo");
  linkData[3] = new Record();
  linkData[3].setAttribute("id", "bar");
  linkData[3].setAttribute("parentId", "zoo");
  tree.setLinkData(linkData);
 
```

```
  - setMultiLinkTree
```
public void setMultiLinkTree(java.lang.Boolean multiLinkTree)

  - getFilteredTree
```
public Tree getFilteredTree(Criteria criteria)
```
    Filters this tree by the provided criteria, returning a new Tree containing just the nodes that match the criteria.
    If filterMode is "keepParents", parents are retained if any of their children match the criteria even if those parents do not match the criteria.
    
    Parameters:

    Returns:
    
    filtered tree
  - getFilteredTree
```
public Tree getFilteredTree(Criteria criteria,
                            TreeFilterMode filterMode,
                            DataSource dataSource)
```

    filtered tree
  - linkNodes
```
public void linkNodes(TreeNode[] nodes)
```
    This method is provided as a mechanism to link new nodes into the tree of modelType "parent". This method takes a list of nodes that must contain at a minimum a unique ID (keyed by idField) and a parent ID (keyed by parentIdField). Based on this information, the list of nodes is integrated into the tree structure.
    
    Parameters:
    
    nodes - list of nodes to link into the tree.
  - getParents
```
public TreeNode[] getParents(TreeNode node)
```
    Given a node, return an array of the node's parents with the immediate parent first. The node itself is not included in the result. For example, for the following tree:
```
 root   foo     bar 
```
    Calling tree.getParents(bar) would return: [foo, root]. Note that the returned array will contain references to the nodes, not the names.
    Parameters:
    
    node - node in question
    
    Returns:
    
    array of node's parents
  - findById
```
public TreeNode findById(java.lang.String id)
```
    Find the node with the specified ID. Specifically, it returns the node whose idField matches the id passed to this method. If the tree is using the "parent" modelType, this lookup will be constant-time. For all other modelTypes, the tree will be searched recursively.
    
    Parameters:
    
    id - ID of the node to return.
    
    Returns:
    
    node with appropriate ID, or null if not found.
  - find
```
public TreeNode find(java.lang.String fieldNameOrPath)
```
    Find a node within this tree using a string path or by attribute value(s). This method can be called with 1 or 2 arguments. If a single String argument is supplied, the value of the argument is treated as the path to the node. if a single argument of type Object is provided, it is treated as a set of field name/value pairs to search for (see com.smartgwt.client..List#find).
    If 2 arguments are supplied, this method will treat the first argument as a fieldName, and return the first node encountered where node[fieldName]matches the second argument. So for example, given this tree:
```
 foo   zoo
   bar   moo     bar 
```
    Assuming your pathDelim is the default / and foo is the name of the root node, then tree.find("foo/moo/bar") would return the bar node under the moo node.
    
    tree.find("name", "bar") would return the first bar node because it is the first one in the list whose name (default value of nameProperty) property matches the value bar. The two argument usage is generally more interesting when your tree nodes have some custom unique property that you wish to search on. For example if your tree nodes had a unique field called "UID", their serialized form would look something like this:
```
 { name: "foo", children: [...], UID:"someUniqueId"} 
```
    You could then call tree.find("UID", "someUniqueId") to find that node. Note that the value doesn't have to be a string - it can be any valid JS value, but since this data generally comes from the server, the typical types are string, number, and boolean.
    
    The usage where you pass a single object is interesting when your tree nodes have a number of custom properties that you want to search for in combination. Say your tree nodes had properties for "color" and "shape"; tree.find({color: "green", shape: "circle"}) would return the first node in the tree where both properties matched.
    
    When searching by path, trailing path delimiters are ignored. So for example tree.find("foo/zoo/bar") is equivalent to tree.find("foo/zoo/bar/")
    Parameters:
    
    fieldNameOrPath - Either the path to the node to be found, or the name of a field which should match the value passed as a second parameter
    
    Returns:
    
    the node matching the supplied criteria or null if not found
  - find
```
public TreeNode find(java.lang.String fieldNameOrPath,
                     java.lang.Object value)
```
    Find a node within this tree using a string path or by attribute value(s).
    
    Overrides:
    
    find in class RecordList
    
    Parameters:
    
    fieldNameOrPath - Either the path to the node to be found, or the name of a field which should match the value passed as a second parameter
    
    value - If specified, this is the desired value for the appropriate field
    
    Returns:
    
    the node matching the supplied criteria or null if not found
    
    See Also:
    
    find(String)
  - find
```
public TreeNode find(java.lang.String propertyName,
                     java.util.Date value)
```
    Find a node within this tree using a string path or by attribute value(s).
    
    Overrides:
    
    find in class RecordList
    
    Parameters:
    
    fieldNameOrPath - Either the path to the node to be found, or the name of a field which should match the value passed as a second parameter
    
    value - If specified, this is the desired value for the appropriate field
    
    Returns:
    
    the node matching the supplied criteria or null if not found

    find(String)
  - getChildren
```
public TreeNode[] getChildren(TreeNode node)
```
    Returns all children of a node. If the node is a leaf, this method returns null.
    
    For load on demand trees (those that only have a partial representation client-side) or for databound tree where the underlying set of children is incomplete, this method will return only those nodes that have already been loaded from the server.
    
    Parameters:
    
    node - The node whose children you want to fetch.
    
    Returns:
    
    List of children for the node (empty List if node is a leaf or has no children)
  - getFolders
```
public TreeNode[] getFolders(TreeNode node)
```
    Returns all the first-level folders of a node.
    
    For load on demand trees (those that only have a partial representation client-side), this method will return only nodes that have already been loaded from the server.
    
    Parameters:
    
    node - node in question
    
    Returns:
    
    List of immediate children that are folders
  - getLeaves
```
public TreeNode[] getLeaves(TreeNode node)
```
    Return all the first-level leaves of a node.
    
    For load on demand trees (those that only have a partial representation client-side), this method will return only nodes that have already been loaded from the server.
    
    Parameters:
    
    node - node in question
    
    Returns:
    
    List of immediate children that are leaves.
  - getDescendants
```
public TreeNode[] getDescendants()
```
    Returns the list of all descendants of a node. Note: this method can be very slow, especially on large trees because it assembles a list of all descendants recursively. Generally, find(java.lang.String) in combination with getChildren(com.smartgwt.client.widgets.tree.TreeNode) will be much faster.
    
    For load on demand trees (those that only have a partial representation client-side), this method will return only nodes that have already been loaded from the server.
    
    Returns:
    
    List of descendants of the node.

```
public static TreeNode nodeForRecord(ListGridRecord record)
```
    A TreeNode and ListGridRecord represent similar datastructures and it is possible that certain TreeGrid operations return a ListGridRecord since TreeGrid extends ListGrid. So in order to call several of the methods in this Tree class, you need to coerce a ListGridRecord to a TreeNode. This can be done by calling this method.
    
    Parameters:
    
    record - the record
    
    Returns:
    
    the TreeNode representation of the record
  - openFolder

    node - node to open
  - getAllNodes
```
public TreeNode[] getAllNodes()
```
    Get all the nodes that exist in the tree under a particular node, as a flat list, in depth-first traversal order.
    
    Returns:
    
    all the nodes that exist in the tree
  - getAllNodes
```
public TreeNode[] getAllNodes(TreeNode node)
```
    Get all the nodes that exist in the tree under a particular node, as a flat list, in depth-first traversal order.
    
    Parameters:
    
    node - optional node to start from. Default is root.
    
    Returns:
    
    all the nodes that exist in the tree
