/**
* Defines a context for maintaining the relation between an entity associated with the Session ultimately owning this
* EntityEntryContext instance and that entity's corresponding EntityEntry. 2 approaches are supported:
* -
* the entity->EntityEntry association is maintained in a Map within this class
*
* -
* the EntityEntry is injected into the entity via it implementing the {@link org.hibernate.engine.spi.ManagedEntity} contract,
* either directly or through bytecode enhancement.
