Detailed Description

Abstract base class for aggregate functions giving an integer array.

Intended use:

Internal

Review Status

Test programs:: tExprGroup

Synopsis

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

If not empty, check if the shape matches that of itsValue.

If itsValue is still empty, it is sized.
