Package org.sqlproc.engine.hibernate

Class HibernateSession

java.lang.Object

org.sqlproc.engine.hibernate.HibernateSession

All Implemented Interfaces:

InvocationHandler

public class HibernateSession
extends Object
implements InvocationHandler

The Hibernate stack implementation of the SQL Engine session contract. In fact it's a proxy to the Session. It's the first parameter to all primary methods in the SqlQueryEngine and SqlCrudEngine.

The implementation is based on the dynamic proxy design pattern provided by the Java API.

The primary contract is the method for the SqlQuery instance creation.

For more info please see the Tutorials.
