Member Function Documentation

virtual void casacore::TableExprGroupRmsDouble::apply ( const TableExprId id)
virtual

Get the operand's value for the given row and apply it to the aggregation.

This function should not be called for lazy classes.

Implements casacore::TableExprGroupFuncBase.

virtual void casacore::TableExprGroupRmsDouble::finish ( )
virtual

If needed, finish the aggregation.

By default nothing is done.

Reimplemented from casacore::TableExprGroupFuncBase.
