AbstractDimensionCalc (Pentaho Community Edition Project: mondrian 9.4.0.0-343 API)

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.
