Class DbSession  view DbSession download DbSession.java

java.lang.Object
  extended byorg.jbpm.util.db.DbSession
public class DbSession
extends java.lang.Object

This class wraps the Hibernate Session. It adds the guarantee that if a method throws an exception, the session will already be closed. Furthermore, this wrapper adds 2 convenience-methods findOne(...) and iterateOne(...) that checks if exactly one object is returned and extracts that single object from the collection.
