Class ManagedSessionContext

java.lang.Object
  extended by org.hibernate.context.ManagedSessionContext
All Implemented Interfaces:
Serializable, CurrentSessionContext

public class ManagedSessionContext
extends Object
implements CurrentSessionContext

Represents a CurrentSessionContext the notion of a contextual session is managed by some external entity (generally some form of interceptor, etc). This external manager is responsible for scoping these contextual sessions appropriately binding/unbinding them here for exposure to the application through SessionFactory.getCurrentSession() calls.

Basically exposes two interfaces.

The underlying storage of the current sessions here is a static ThreadLocal-based map where the sessions are keyed by the the owning session factory.
