Detailed Description

Persistent store abstract base class. It provides the behaviour for setting and retrieving the root stream id.

Before closing a persistent store, the root stream id must be set. After opening a persistent store, the first thing done is to look up the root stream id. The root stream can then be opened and data read from the store.
