CDictionaryStore Class Reference

class CDictionaryStore : public CBase

Dictionary store interface.

This is an abstract class which provides the necessary interface for using concrete dictionary stores.

A dictionary store is a store where a stream is accessed by UID (TUid), rather than directly by stream id (TStreamId).

This type of store contains streams in the usual way but, in addition, the root stream is a stream dictionary. The stream dictionary provides a list of two-way associations between unique identifiers and stream ids.

Note that a dictionary store object does not derive from CStreamStore, but owns a persistent store and a stream dictionary as part of its implementation.
