java.lang.Objectorg.eclipse.datatools.connectivity.oda.spec.result.AggregateExpression
org.eclipse.datatools.connectivity.oda.spec.result.CustomAggregate
public class CustomAggregate
Represents an instance of custom aggregate expression contributed by an extension of the org.eclipse.datatools.connectivity.oda.dynamicResultSet extension point.
| Method Summary | |
|---|---|
|  boolean | canIgnoreDuplicateValues()Indicates whether this aggregate type is capable of ignoring duplicate values of its input variable. | 
|  boolean | canIgnoreNullValues()Indicates whether this aggregate type is capable of ignoring null values of its input variable. | 
|  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 dynamicResultSet extension that declares this custom expression type. | 
|  AggregateDefinition | 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 expression type. | 
|  java.lang.String | getQualifiedId()Returns the qualified id of this expression type. | 
|  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,
                      java.lang.String propertyName,
                      java.lang.Object data) | 
|  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. |
