Enum Constant Detail

PARENT

public static final TreeModelType PARENT

In this model, each node has an ID unique across the whole tree and a parent ID that points to its parent. The name of the unique ID property can be specified via Tree.idField and the name of the parent ID property can be specified via Tree.parentIdField. The initial set of nodes can be passed in as a list to Tree.data and also added as a list later via Tree.linkNodes(). Whether or not a given node is a folder is determined by the value of the property specified by Tree.isFolderProperty.

The "parent" modelType is best for integrating with relational storage (because nodes can map easily to rows in a table) and collections of Beans and is the model used for DataBound trees.

If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "parent".

CHILDREN

public static final TreeModelType CHILDREN

In this model, nodes specify their children as a list of nodes. The property that holds the children nodes is determined by Tree.childrenProperty. Nodes are not required to have an ID that is unique across the whole tree (in fact, no ID is required at all). Node names (specified by the Tree.nameProperty, unique within their siblings, are optional but not required. Whether or not a given node is a folder is determined by the presence of the children list (Tree.childrenProperty).

If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "children".

Method Detail

values

public static TreeModelType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TreeModelType c : TreeModelType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TreeModelType valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getValue

public java.lang.String getValue()

Specified by:

getValue in interface ValueEnum
