Detailed Description

Abstract base class for aggregate functions giving a dcomplex scalar.

Synopsis

This class is derived from TableExprGroupFuncBase and acts as the abstract base class for aggregate functions resulting in a dcomplex scalar.
Derived classes can use itsValue to contain the aggregated value. It that case they do not need to implement the get function.
