Detailed Description

template<typename T>
class casacore::ConcatScalarColumn< T >

A typed column in a concatenated table.

Intended use:

Internal

Review Status

Reviewed By:: UNKNOWN

Prerequisite

Etymology

ConcatTable represents a column in a ConcatTable. A ConcatTable is a table referencing another table, usually as the result of a select, etc..

Synopsis

ConcatColumn handles the access of a column in a ConcatTable. It calls the corresponding function in the referenced column while converting the given row number to the row number in the referenced table.

Motivation

This class is untyped, i.e. not templated. Every call is sent to the underlying referenced BaseColumn which is typed by the virtual function mechanism. A ConcatColumn can never be used directly. A user always has to construct a typed ArrayColumn or ScalarColumn object to access a column. This means everyting is fully type safe.

To Do

Act upon removal of rows or the underlying column

template<typename T >

casacore::ConcatScalarColumn< T >::ConcatScalarColumn	(	const BaseColumnDesc *	,
		ConcatTable *
	)

Construct the ConcatColumn.

It will point to the given column description, ConcatTable and referenced column. The ConcatTable will be used to convert the rownr to the rownr in the referenced column.
