Synopsis

TaQLJoinArrayColumn contains the TableExprNodeColumn object for an array column in a join table. It is used to find a value in the join column for a row in the main table. It uses the TableParseJoin object to find the row in the join table given the row in the main table.

◆ clear()

void casacore::TaQLJoinColumnBool::clear ( )
overridevirtual

Clear the internal data vector (in derived classes).

Reimplemented from casacore::TaQLJoinColumn.

◆ getBool()

Bool casacore::TaQLJoinColumnBool::getBool ( const TableExprId &  id)
overridevirtual

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.
