Class AbstractMemberCalc

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

All Implemented Interfaces:

Calc, MemberCalc

Direct Known Subclasses:

DimensionCurrentMemberCalc, DimensionCurrentMemberFunDef.CalcImpl, HierarchyCurrentMemberFunDef.CalcImpl

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.
