AbstractVoidCalc (Pentaho Community Edition Project: mondrian 9.3.0.0-424 API)

java.lang.Object
- mondrian.calc.impl.AbstractCalc
- - mondrian.calc.impl.GenericCalc
  - - mondrian.calc.impl.AbstractVoidCalc

All Implemented Interfaces:

BooleanCalc, Calc, DateTimeCalc, DimensionCalc, DoubleCalc, HierarchyCalc, IntegerCalc, LevelCalc, MemberCalc, StringCalc, TupleCalc, VoidCalc
```
public class AbstractVoidCalc
extends GenericCalc
implements VoidCalc
```
Abstract implementation of the VoidCalc interface.
The derived class must implement the GenericCalc.evaluateVoid(mondrian.olap.Evaluator) method, and the evaluate(mondrian.olap.Evaluator) method will call it and return null.
