Package org.datanucleus.store
Class AbstractStoreManager

org.datanucleus.properties.PropertyStore
org.datanucleus.store.AbstractStoreManager
- All Implemented Interfaces:
StoreManager
An abstract representation of a Store Manager.
Manages the persistence of objects to the store.
Will be implemented for the type of datastore (RDBMS, ODBMS, etc) in question.
The store manager's responsibilities include:
- Creating and/or validating datastore tables according to the persistent classes being accessed by the application.
- Serving as the primary intermediary between StateManagers and the database.
- Serving as the base Extent and Query factory.
A store manager's knowledge of its contents is typically not complete. It knows about the classes that it has encountered in its lifetime. The ExecutionContext can make the StoreManager aware of a class, and can check if the StoreManager knows about a particular class.
