SessionFactory (Red Hat JBoss Enterprise Application Platform 7.1.0.Beta1 public API)

All Superinterfaces:

AutoCloseable, Closeable, Referenceable, Serializable

All Known Subinterfaces:

SessionFactoryImplementor

All Known Implementing Classes:

SessionFactoryDelegatingImpl, SessionFactoryImpl
```
public interface SessionFactory
extends Referenceable, Serializable, Closeable
```
The main contract here is the creation of Session instances. Usually an application has a single SessionFactory instance and threads servicing client requests obtain Session instances from this factory.
The internal state of a SessionFactory is immutable. Once it is created this internal state is set. This internal state includes all of the metadata about Object/Relational Mapping.
Implementors must be threadsafe.
