public class Operator

extends BaseObject

implements DerivedMeasureInput

The calculation specification in a DerivedMeasure.

A DerivedMeasure owns an Operator, and it can include a text expression of OLAP DML commands.

An Operator consists of one or more input specifications and a calculation method on each input. The input can be any object that implements the DerivedMeasureInput interface. Implementing objects are: hierarchies, levels within hierarchies, levels, measures, and attributes.

Since Operator also implements the DerivedMeasureInput interface, an Operator can include a series of Operator objects.

The Operator class supports the following calculation methods:

   Add
   Subtract 
   Multiply
   Divide
   Power
