Class HibernateTransaction

public class HibernateTransaction
extends Object

A Hibernate transaction in the platform is always tied to a single thread. Every time a thread is executed an instance of this class is created and bounded to the current thread. The standard way to interact with the underlying transaction is to make use of the HibernateTxFragment idiom.
