Detailed Description

Base class for the Data Manager Accessor classes.

Intended use:

Internal

Review Status

Prerequisite

• DataManager

Synopsis

The Table system has one or more data managers underneath. Once a table is constructed, these data managers are invisible and there is no way to get access to them. However, sometimes limited access to them is needed (e.g. to set the size of an internal cache).

This class should be used as the base class for specialized Data Manager Accessor classes (e.g. class

ROIncrementalStManAccessor . This base class provides the functionality to get the DataManager object for a given column.

Motivation

This base class makes it possible that every derived class can get the data manager, because RODataManAccessor is a friend of class Table. Otherwise all accessor classes needed to be friend of Table.
