Member Function Documentation

Array<Bool> casa::TableExprNodeArrayPart::getArrayBool ( const TableExprId & id ) [virtual]

Get an array 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.

Array<MVTime> casa::TableExprNodeArrayPart::getArrayDate ( const TableExprId & id ) [virtual]

Reimplemented from casa::TableExprNodeRep.

Array<DComplex> casa::TableExprNodeArrayPart::getArrayDComplex ( const TableExprId & id ) [virtual]

The default implementation of getArrayDComplex does getArrayDouble and converts the result.

Reimplemented from casa::TableExprNodeArray.

Array<Double> casa::TableExprNodeArrayPart::getArrayDouble ( const TableExprId & id ) [virtual]

Reimplemented from casa::TableExprNodeRep.

Array<Int64> casa::TableExprNodeArrayPart::getArrayInt ( const TableExprId & id ) [virtual]

Reimplemented from casa::TableExprNodeRep.

Array<String> casa::TableExprNodeArrayPart::getArrayString ( const TableExprId & id ) [virtual]

Reimplemented from casa::TableExprNodeRep.

Bool casa::TableExprNodeArrayPart::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.

Array<Bool> casa::TableExprNodeArrayPart::getColumnBool ( ) [virtual]

Get the value of the expression evaluated for the entire column.

The data of function called should match the data type as returned by function getColumnDataType.

Reimplemented from casa::TableExprNodeRep.

Array<Complex> casa::TableExprNodeArrayPart::getColumnComplex ( ) [virtual]

Reimplemented from casa::TableExprNodeRep.

Bool casa::TableExprNodeArrayPart::getColumnDataType ( DataType & ) const [virtual]

Get the data type of this column (if possible).

It returns with a False status when the index is not constant (that means that the index can vary with row number).

Reimplemented from casa::TableExprNodeRep.

Array<DComplex> casa::TableExprNodeArrayPart::getColumnDComplex ( ) [virtual]
