org.apache.jackrabbit.core.persistence.PersistenceManager
Persistence manager interface. Persistence managers are internal Jackrabbit components that handle the persistent storage of content nodes and properties. A persistence manager knows how to retrieve the persistent states of content items and how to atomically save a set of changes to the persistent state.
Each workspace of a Jackrabbit content repository uses separate persistence manager to store the content in that workspace. Also the Jackrabbit version handler uses a separate persistence manager. The persistence managers in use are configured in the Jackrabbit XML configuration files. The configured persistence managers are instantiated and initialized using the JavaBeans conventions.
Persistence manager life cycle

The life cycle of a persistence manager instance contains four phases:
1. Instantiation, where the instance is created and possible configuration properties are set using the JavaBean conventions. During this phase the persistence manager should not attempt to reference any external resources.
2. Initialization, where the {@link #init(PMContext) init} methodis invoked to bind the persistence manager with a given {@link PMContext context}.
3. Normal usage, where the various create, load, exists, and store methods of the persistence manager are used to manage the persistent content items.
4. Closing, where the {@link #close() close} method is invokedto close the persistence manager and release all acquired resources.
