org.nanocontainer.persistence.hibernate.classic
Class SessionDelegator

java.lang.Object
  extended by org.nanocontainer.persistence.hibernate.classic.SessionDelegator
All Implemented Interfaces:
Serializable, net.sf.hibernate.Session
Direct Known Subclasses:
FailoverSessionDelegator
public abstract class SessionDelegator
extends Object
implements net.sf.hibernate.Session

Abstract base class for session delegators, which delegates all calls to session obtained by implementing class. Also does error handling. All methods are just delegations to a Hibernate session.
