mondrian.calc.impl
Class AbstractDoubleCalc

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

All Implemented Interfaces:

Calc, DoubleCalc

Direct Known Subclasses:

AggregateFunDef.AggregateCalc

public abstract class AbstractDoubleCalc
extends AbstractCalc
implements DoubleCalc

Abstract implementation of the DoubleCalc interface.

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