String comparison IN in table select expression tree.

Date Reviewed:



This class represents an IN comparison in a table select expression tree. This is defined for all data types. Only the Bool get function is defined, because the result of a compare is always a Bool.

Member Function Documentation

Bool casacore::TableExprNodeINString::getBool ( const TableExprId id)

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 casacore::TableExprNodeRep.
