org.eclipse.datatools.connectivity.oda.spec.result.filter.CustomExpression
public class CustomExpression
Represents an instance of custom filter expression contributed by an extension of the org.eclipse.datatools.connectivity.oda.dynamicResultSet extension point.
| Method Summary | |
|---|---|
|  java.lang.Object | getData(java.lang.String key)Gets the value of an extension-defined property of the specified name. | 
|  java.lang.String | getDeclaringExtensionId()Gets the unique id of the ODA dynamicResultSet extension that declares this custom expression type. | 
|  FilterExpressionDefinition | getDefinition()Gets the definition of this expression's capabilities and metadata, as registered by the provider in its extension of the org.eclipse.datatools.connectivity.oda.dynamicResultSet extension point. | 
|  java.lang.String | getId()Gets the expression id. | 
|  java.lang.String | getName()Gets the name of this filter expression type. | 
|  java.lang.String | getQualifiedId()Returns the qualified id of this expression type. | 
|  boolean | isNegatable()Indicates whether this expression can be negated. | 
|  boolean | isOptionable()Indicates whether this expression can be optional and skipped in a filter specification if all its expected argument values are null. | 
|  void | setData(java.lang.String key,
        java.lang.Object value)Sets the value of an extension-defined property of the specified name. | 
|  void | setInitializationData(org.eclipse.core.runtime.IConfigurationElement exprElement,

|  boolean | supportsDataSetType(java.lang.String odaDataSourceId,
                    java.lang.String odaDataSetId)Indicates whether this expression can be applied to the specified data set type within the data source type. | 
|  boolean | supportsDataSetType(SupportedDataSetType dataSetType)Indicates whether this expression can be applied to the specified data set type. | 
|  void | validateSyntax(ValidationContext context)Performs syntactic validation of this expression in the specified context. |
