Examples of org.hibernate.engine.spi.ManagedEntity

org.hibernate.engine.spi.ManagedEntity
Specialized {@link Managed} contract for entity classes. Essentially provides access to informationabout an instance's association to a Session/EntityManager. Specific information includes:
- the association's {@link EntityEntry} (by way of {@link #$$_hibernate_getEntityEntry} and{@link #$$_hibernate_setEntityEntry}). EntityEntry describes states, snapshots, etc.
- link information. ManagedEntity instances are part of a "linked list", thus link information describes the next and previous entries/nodes in that ordering. See {@link #$$_hibernate_getNextManagedEntity}, {@link #$$_hibernate_setNextManagedEntity}, {@link #$$_hibernate_getPreviousManagedEntity}, {@link #$$_hibernate_setPreviousManagedEntity}
