Detailed Description

A column in a concatenated table

Internal

Review Status

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.
