Bool casa::TableExprNodeEQDComplex::getBool ( const TableExprId & id ) [virtual]

Is the expression a column aggregate function?

virtual Bool isAggregate() const; Get a scalar value for this node in the given row. The appropriate functions are implemented in the derived classes and will usually invoke the get in their children and apply the operator on the resulting values.

Reimplemented from casa::TableExprNodeRep.
