Abstract base class for aggregate functions giving a dcomplex scalar.
Internal
This class is derived from TableExprGroupFuncBase and act 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.
