Member Function Documentation

virtual MArray<Bool> casacore::TableExprNodeRecordFieldArray::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.

virtual MArray<DComplex> casacore::TableExprNodeRecordFieldArray::getArrayDComplex

(

const TableExprId &

id

)

[virtual]

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

Reimplemented from casacore::TableExprNodeArray.

virtual MArray<Double> casacore::TableExprNodeRecordFieldArray::getArrayDouble

(

const TableExprId &

id

)

[virtual]

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

Reimplemented from casacore::TableExprNodeArray.

virtual MArray<Int64> casacore::TableExprNodeRecordFieldArray::getArrayInt

(

const TableExprId &

id

)

[virtual]

Reimplemented from casacore::TableExprNodeRep.

virtual MArray<String> casacore::TableExprNodeRecordFieldArray::getArrayString

(

const TableExprId &

id

)

[virtual]

Reimplemented from casacore::TableExprNodeRep.

const RecordInterface& casacore::TableExprNodeRecordFieldArray::getRecord

(

const TableExprId &

id

)

const [protected]

Get the record for the last field number, thus going through all subrecords for the other field numbers.

virtual const IPosition& casacore::TableExprNodeRecordFieldArray::getShape

(

const TableExprId &

id

)

[virtual]

Get the shape of the array in the given row.

This default implementation evaluates the value and returns its shape.

Reimplemented from casacore::TableExprNodeArray.

virtual Bool casacore::TableExprNodeRecordFieldArray::isDefined

(

const TableExprId &

id

)

[virtual]

Is the value in the given row defined? The default implementation returns True.

Reimplemented from casacore::TableExprNodeRep.
