Class HibernateLongSessionContext

java.lang.Object

to.etc.webapp.query.QAbstractDataContext

to.etc.domui.hibernate.generic.BuggyHibernateBaseContext

to.etc.domui.hibernate.generic.HibernateLongSessionContext

All Implemented Interfaces:

AutoCloseable, IConversationStateListener, to.etc.webapp.query.QDataContext

public class HibernateLongSessionContext
extends BuggyHibernateBaseContext

A context that keeps the session alive but in disconnected mode while running. The session is put into MANUAL flush mode, and the database connection is closed every time the conversation is detached. Only the last phase of a conversation may commit and flush changes to the database; all intermediary flushes will be rolled back (and of course Hibernate will not see it).
