Detailed Description

Abstract base class for aggregate functions giving a double array.

Intended use:


Review Status

Test programs:


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

Member Function Documentation

Bool casacore::TableExprGroupFuncArrayDouble::checkShape ( const MArrayBase arr,
const String func 

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

If itsValue is still empty, it is sized.

virtual MArray<Double> casacore::TableExprGroupFuncArrayDouble::getArrayDouble ( const vector< TableExprId > &  )
