Member Function Documentation

MArray<Bool> casacore::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 casacore::TableExprNodeRep.

MArray<MVTime> casacore::TableExprNodeArrayPart::getArrayDate

(

const TableExprId &

id

)

[virtual]

Reimplemented from casacore::TableExprNodeRep.

MArray<DComplex> casacore::TableExprNodeArrayPart::getArrayDComplex

(

const TableExprId &

id

)

[virtual]

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

Reimplemented from casacore::TableExprNodeArray.

MArray<Double> casacore::TableExprNodeArrayPart::getArrayDouble

(

const TableExprId &

id

)

[virtual]

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

Reimplemented from casacore::TableExprNodeArray.

MArray<Int64> casacore::TableExprNodeArrayPart::getArrayInt

(

const TableExprId &

id

)

[virtual]

Reimplemented from casacore::TableExprNodeRep.

MArray<String> casacore::TableExprNodeArrayPart::getArrayString

(

const TableExprId &

id

)

[virtual]

Reimplemented from casacore::TableExprNodeRep.

Bool casacore::TableExprNodeArrayPart::getBool

(

const TableExprId &

id

)

[virtual]

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.

Array<Bool> casacore::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 casacore::TableExprNodeRep.

Array<Complex> casacore::TableExprNodeArrayPart::getColumnComplex

(

const Vector< uInt > &

rownrs

)

[virtual]

Reimplemented from casacore::TableExprNodeRep.

Bool casacore::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 casacore::TableExprNodeRep.

Array<DComplex> casacore::TableExprNodeArrayPart::getColumnDComplex

(

const Vector< uInt > &

rownrs

)

[virtual]

Reimplemented from casacore::TableExprNodeRep.

Array<Double> casacore::TableExprNodeArrayPart::getColumnDouble

(

const Vector< uInt > &

rownrs

)

[virtual]

Reimplemented from casacore::TableExprNodeRep.

Array<Float> casacore::TableExprNodeArrayPart::getColumnFloat

(

const Vector< uInt > &

rownrs

)

[virtual]

Reimplemented from casacore::TableExprNodeRep.

Array<Int> casacore::TableExprNodeArrayPart::getColumnInt

(

const Vector< uInt > &

rownrs

)

[virtual]

Reimplemented from casacore::TableExprNodeRep.

const TableExprNodeArrayColumn * casacore::TableExprNodeArrayPart::getColumnNode

(

)

const [inline]

Get the array column node.

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

Array<Short> casacore::TableExprNodeArrayPart::getColumnShort

(

const Vector< uInt > &

rownrs

)

[virtual]

Reimplemented from casacore::TableExprNodeRep.

Array<String> casacore::TableExprNodeArrayPart::getColumnString

(

const Vector< uInt > &

rownrs

)

[virtual]

Reimplemented from casacore::TableExprNodeRep.

const Vector< uInt > &

rownrs

)

[virtual]

Reimplemented from casacore::TableExprNodeRep.

Array<uInt> casacore::TableExprNodeArrayPart::getColumnuInt

(

const Vector< uInt > &

rownrs

)

[virtual]
