```
public class SimpleType
extends BaseClass
```
An atomic type such as a string or number, that is generally stored, displayed and manipulated as a single value.
SimpleTypes can be created at any time, and subsequently referred to as a field type in DataSources and DataBoundComponents. This allows you to define validation, formatting and editing behaviors for a type to be reused across all DataBoundComponents.
The SimpleType class also allows data to be stored in some opaque format but treated as simple atomic values as far as Smart GWT components are concerned by implementing getAtomicValue() and updateAtomicValue() methods. For example, if some record has a field value set to a javascript object with the following properties:
```
  { stringValue:"A String", length: 9 }
  
```
this value could be treated as a simple string by defining a SimpleType with inheritsFrom set to "text" and a custom getAtomicValue() method that simply extracted the "stringValue" attribute from the data object. DataBoundComponents would then display the string value, and use it for sorting and other standard databinding features.
Note that the term "simpleType" is used in the same sense as in XML Schema, and XMLTools.loadXMLSchema() will create new SimpleType definitions.
When using the Smart GWT Server, SimpleTypes can be defined server-side, and should be defined server-side if validators are going to be declared so that the server will enforce validation. To define server-side SimpleTypes using Component XML you should create file {typeName}.type.xml in the following format:
```
    <SimpleType name="{typeName}" inheritsFrom="{otherSimpleType}" 
                   editorType="{FormItemClassName}">
      <validators>
        
      </validators>
    </SimpleType>
  
```
.. and place this file alongside your DataSource files (.ds.xml) files - in any of folders listed in project.datasources property in server.properties.
SimpleTypes can be loaded via DataSourceLoader or loadDS JSP tags and should be loaded before the definitions of any DataSources that use them (so generally put all SimpleType definitions first).
Define validators in the server-side type definition, for example:
```
    <SimpleType name="countryCodeType" inheritsFrom="text">
      <validators>
        <validator type="lengthRange" min="2" max="2"
          errorMessage="Length of country code should be equal to 2." />
        <validator type="regexp" expression="[A-Z][A-Z]"
          errorMessage="CountryCode should have only uppercase letters." />
      </validators>
    </SimpleType>
  
```
For client-side formatters, add these to the type definition after loading it from the server, for example:
```
      SimpleType.getType("independenceDateType").setShortDisplayFormatter(new SimpleTypeFormatter() {
        public String format(Object value, DataClass field, DataBoundComponent component, Record record) {
          if (value == null) return null;
          return "<i>" + (((java.util.Date) value).getYear() + 1900) + "</i>";
        }
      });
    
```
Note that formatters must be added to the SimpleType definition before any DataBoundComponent binds to a DataSource that uses the SimpleType.
An example is here.

    Default FormItem configuration for editing values of this type.
    You can create a simple custom FormItem by adding default icons that launch custom value picking dialogs (an example is in the QuickStart Guide, Chapter 9, Extending Smart GWT).
    Note: The FormItem passed to setEditorProperties() is used as a "template" to create a FormItem.
    For an overview of the template rules, reflection requirements when trying to assign an edit Formitem by type, and an understanding of how the various setEditorProperties() calls on different classes relate to each other in determining what configuration ultimately gets applied to the edit FormItem, see DataSourceField.setEditorProperties(FormItem).
    
    Parameters:
    
    editorProperties - FormItem with default properties to use when editing
    
    Throws:

```
public void setEditorType(java.lang.String editorType)
```
    Set the default FormItem class to be used whenever a value of this type is edited (whether in a grid, form, or other component).
    If unset, a FormItem will be automatically chosen.
    Note: The editorType must be registered for use with the reflection mechanism. By doing so, you avoid the limitations of setEditorProperties(FormItem). If the editorType cannot be resolved via reflection, this method will still work if editorType refers to a built-in SmartGWT framework class, such as com.smartgwt.client.widgets.form.fields.SetFilterItem.

    Normal formatter for values of this type used in a StaticTextItem or DetailViewer.
    A formatter can make itself configurable on a per-component or per-field basis by checking properties on the component or field. For example, a formatter for account IDs may want to omit a prefix in views where it is redundant, and could check a flag detailViewer.omitAccountIdPrefix for this purpose.
    
    Parameters:
    
    formatter - the formatter
  - setShortDisplayFormatter
```
public void setShortDisplayFormatter(SimpleTypeFormatter formatter)
```
    Formatter for values of this type when compact display is required, for example, in a ListGrid or TreeGrid.
    A formatter can make itself configurable on a per-component or per-field basis by checking properties on the component or field. For example, a formatter for account IDs may want to omit a prefix in views where it is redundant, and could check a flag listGridField.omitAccountIdPrefix for this purpose.
    
    Parameters:
    
    formatter - the formatter
  - setEditFormatter
```
public void setEditFormatter(SimpleTypeFormatter formatter)
```
    Formatter for values of this type when displayed in a freeform text editor such as a TextItem
    See also #parseInput for parsing an edited text value back to a data value.
    
    Parameters:
    
    formatter - the formatter
  - setEditParser
```
public void setEditParser(SimpleTypeParser parser)
```
    Specify a parser to convert some user-edited value to an underlying data value of this type. This parser is called when storing out values edited in a freeform editor such as a TextItem. Typically this will convert from the format produced by #editFormatter back to a data value.
    
    Parameters:
    
    parser - the parser
  - setSkipConvertOpaqueValues
```
public static void setSkipConvertOpaqueValues(java.lang.Boolean convert)
```
    Tells the atomic values subsystem whether to skip conversion of the incoming opaque value to a Java object when calling user getAtomicValue() and updateAtomicValue() methods. By default, we do convert the opaque value, and your methods will be passed a Java object - typically a Map of native Java types. Passing true to this method switches off conversion, and your methods will be passed a JavaScriptObject
    
    Parameters:
    
    convert - Whether the atomic values subsystem should skip conversion of opaque values to native Java types
  - getSkipConvertOpaqueValues
```
public static java.lang.Boolean getSkipConvertOpaqueValues()
```

By default, we do convert the opaque value, and your methods will be passed a Java object - typically a Map of native Java types. Passing false to this mehtod switches off conversion, and your methods will be passed a JavaScriptObject
    
    Returns:
    
    Boolean indicating whether the atomic values subsystem will convert opaque values to native Java types
  - setSimpleTypeValueExtractor
```
public void setSimpleTypeValueExtractor(SimpleType.SimpleTypeValueExtractor extractor)
```
    Specify an extractor to extract an atomic value (such as a string or number) from some arbitrary live data value. If defined this method will be called for every field value of the specified type in order to convert from the raw data value to an atomic type to be used for standard DataBinding features such as sorting and editing.
    
    Parameters:
    
    extractor - the extractor
  - setSimpleTypeValueUpdater
```
public void setSimpleTypeValueUpdater(SimpleType.SimpleTypeValueUpdater updater)
```
    Specify an updater to update a live data value with an edited atomic value (such as a string or number).
