| Class | Description | 
|---|---|
| AdvancedCriteria | 
 AdvancedCriteria is a format for representing search criteria which may include
  operators on field values such as "less than", or may include sub-clauses such as several 
  criteria applied to fields joined by an "OR" operator. 
 | 
| Criterion | 
 An object representing a criterion to apply to a record. 
 | 
| DataSource | 
 A DataSource is data-provider-independent description of a set of objects that will be loaded,
 edited and saved within the user interface of your application. 
 | 
| DataSourceField | 
 Metadata about a DataSourceField, including its type and validators. 
 | 
| DSRequestModifier | 
 An object that modifies a dsRequest based on several available 
  values, including preceding responses from the same queue. 
 | 
| 
 A  
Mail object describes an email that will be sent automatically by the  Smart GWT
 Server as part of a normal DataSource operation. | 
|
| OperationBinding | 
 An operationBinding tells a DataSource how to execute one of the basic DS operations: fetch,
 add, update, remove. 
 | 
| Operator | 
 Specification of an operator for use in filtering, for example "equals". 
 | 
| ServerObject | 
 The ServerObject tells the ISC server how to find or create a server-side object involved in
  
DMI (Direct Method Invocation). | 
| SimpleType | 
 An atomic type such as a string or number, that is generally stored, displayed and
  manipulated as a single value. 
 | 
| Validator | 
 A validator describes a check that should be performed on a value the user is trying to
 save. 
 | 
| VisibleMethod | 
 Defines the method of the  
ServerObject if it appears
 in an Application declaration file. | 
Each Java Class here represents an XML element, and each field is a setting that can be specified as either an attribute or a subelement.
For example, DataSource.canMultiSort can be set like this:
<DataSource canMultiSort="true"/>
 Or like this:
 
<DataSource>
    <canMultiSort>true</canMultiSort>
</DataSource>
 When a class in this package has a field that is an Array of another class, it means there is
 a containing XML tag named after the field, then several tags named after the class.  For
 example, DataSource.operationBindings is an Array of OperationBinding.  The XML for this is:
 
<DataSource>
    <operationBindings>
        <operationBinding operationType="fetch">
            ... various operationBinding settings ...
        </operationBinding>
    </operationBindings>
</DataSource>
 If the field is not an Array, it means there should be a singular tag.  For example,
 OperationBinding.mail:
 
<DataSource>
    <operationBindings>
        <operationBinding operationType="add">
            <mail to="admin@company.com" templateFile="messageTemplate.txt"/>
        </operationBinding>
    </operationBindings>
</DataSource>
 
 DataSource files and other Component XML files can be localized using resource bundles - 
 see this overview for details.
