public class PreComputeClause

extends BaseObject

A set of dimension members in an AggregationHierarchySpecification for which data should be precalculated with the OLAP DML AGGREGATE command.

A PreComputeClause is implemented as a precompute clause in an OLAP DML RELATION statement. Its owning AggregationDefinition is implemented as the aggmap that includes the RELATION statement.

PreComputeClause uses a DimensionMemberSelection to specify a set of dimension members to be included in the aggregation or excluded from the aggregation.

For more information, see the OLAP DML Reference.

public void removeDimensionMemberExpression(DimensionMemberExpression input)

Removes a DimensionMemberExpression.

Parameters:

input - The DimensionMemberExpression to remove.

getDimensionMemberExpressions

public java.util.Vector getDimensionMemberExpressions()

Returns the DimensionMemberExpression objects associated with the PreComputeClause.

Returns:

A Vector of DimensionMemberExpression object.

WriteToXML

public java.lang.String WriteToXML()

Returns the PreComputeClause as an XML string.

Overrides:

WriteToXML in class BaseObject

Returns:

A String containing the XML that represents the PreComputeClause.

createDimensionMemberExpression

public DimensionMemberExpression createDimensionMemberExpression()

Creates a DimensionMemberExpression for the PreComputeClause.

Returns:

The new DimensionMemberExpression.
