mondrian.calc.impl
Class AbstractBooleanCalc

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

All Implemented Interfaces:

BooleanCalc, Calc

public abstract class AbstractBooleanCalc
extends AbstractCalc
implements BooleanCalc

Abstract implementation of the BooleanCalc interface.

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