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 ( const Vector< uInt > & rownrs ) [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 ( const Vector< uInt > & rownrs ) [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 ( const Vector< uInt > & rownrs ) [virtual]

Reimplemented from casa::TableExprNodeRep.

Array<Double> casa::TableExprNodeArrayPart::getColumnDouble ( const Vector< uInt > & rownrs ) [virtual]

Reimplemented from casa::TableExprNodeRep.

Array<Float> casa::TableExprNodeArrayPart::getColumnFloat ( const Vector< uInt > & rownrs ) [virtual]

Reimplemented from casa::TableExprNodeRep.

Array<Int> casa::TableExprNodeArrayPart::getColumnInt ( const Vector< uInt > & rownrs ) [virtual]

Reimplemented from casa::TableExprNodeRep.

const TableExprNodeArrayColumn * casa::TableExprNodeArrayPart::getColumnNode ( ) const [inline]

Get the array column node.

It returns 0 if the parent object is no array column.

Definition at line 811 of file ExprNodeArray.h.

Array<Short> casa::TableExprNodeArrayPart::getColumnShort ( const Vector< uInt > & rownrs ) [virtual]

Reimplemented from casa::TableExprNodeRep.

Array<String> casa::TableExprNodeArrayPart::getColumnString ( const Vector< uInt > & rownrs ) [virtual]

Reimplemented from casa::TableExprNodeRep.

Array<uChar> casa::TableExprNodeArrayPart::getColumnuChar ( const Vector< uInt > & rownrs ) [virtual]

Reimplemented from casa::TableExprNodeRep.

Array<uInt> casa::TableExprNodeArrayPart::getColumnuInt ( const Vector< uInt > & rownrs ) [virtual]

Reimplemented from casa::TableExprNodeRep.

Array<uShort> casa::TableExprNodeArrayPart::getColumnuShort ( const Vector< uInt > & rownrs ) [virtual]

Reimplemented from casa::TableExprNodeRep.

MVTime casa::TableExprNodeArrayPart::getDate ( const TableExprId & id ) [virtual]

Reimplemented from casa::TableExprNodeRep.

DComplex casa::TableExprNodeArrayPart::getDComplex ( const TableExprId & id ) [virtual]

Reimplemented from casa::TableExprNodeRep.

Double casa::TableExprNodeArrayPart::getDouble ( const TableExprId & id ) [virtual]

Reimplemented from casa::TableExprNodeRep.

const TableExprNodeIndex * casa::TableExprNodeArrayPart::getIndexNode ( ) const [inline]

Get the index node.

Definition at line 805 of file ExprNodeArray.h.

Int64 casa::TableExprNodeArrayPart::getInt ( const TableExprId & id ) [virtual]

Reimplemented from casa::TableExprNodeRep.

String casa::TableExprNodeArrayPart::getString ( const TableExprId & id ) [virtual]

Reimplemented from casa::TableExprNodeRep.

void casa::TableExprNodeArrayPart::show	(	ostream &	os,
		uInt	indent
	)		const `[virtual]`

Show the node.
