Description

Prerequisite

Synopsis

This class represents a scalar column in a table select expression tree. When the select expression gets evaluated, the value of the given row in the column is used.

Member Description

TableExprNodeRecordField (DataType dtype, const Block<Int>& fieldNumbers)

~TableExprNodeRecordField()

virtual const IPosition& getShape (const TableExprId& id)

virtual Bool isDefined (const TableExprId& id)

virtual Bool getBool (const TableExprId& id)

virtual Double getDouble (const TableExprId& id)

virtual DComplex getDComplex (const TableExprId& id)

virtual String getString (const TableExprId& id)

const RecordInterface& getRecord (const TableExprId& id) const

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