mondrian.calc.impl
Class AbstractTupleCalc

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

All Implemented Interfaces:

Calc, TupleCalc

Direct Known Subclasses:

TupleFunDef.CalcImpl

public abstract class AbstractTupleCalc
extends AbstractCalc
implements TupleCalc

Abstract implementation of the TupleCalc interface.

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