mondrian.calc.impl

Class AbstractDimensionCalc

java.lang.Object

mondrian.calc.impl.AbstractCalc

mondrian.calc.impl.AbstractDimensionCalc

All Implemented Interfaces:

Calc, DimensionCalc

Direct Known Subclasses:

HierarchyDimensionFunDef.CalcImpl

public abstract class AbstractDimensionCalc
extends AbstractCalc
implements DimensionCalc

Abstract implementation of the DimensionCalc interface.

The derived class must implement the DimensionCalc.evaluateDimension(mondrian.olap.Evaluator) method, and the evaluate(mondrian.olap.Evaluator) method will call it.
