AbstractMemberCalc (Pentaho Community Edition Project: mondrian 10.1.0.1-323 API)

java.lang.Object
- mondrian.calc.impl.AbstractCalc
- - mondrian.calc.impl.AbstractMemberCalc

All Implemented Interfaces:

Calc, MemberCalc

Direct Known Subclasses:

HierarchyCurrentMemberFunDef.CalcImpl, HierarchyCurrentMemberFunDef.FixedCalcImpl
```
public abstract class AbstractMemberCalc
extends AbstractCalc
implements MemberCalc
```
Abstract implementation of the MemberCalc interface.
The derived class must implement the MemberCalc.evaluateMember(mondrian.olap.Evaluator) method, and the evaluate(mondrian.olap.Evaluator) method will call it.
