Examples of org.hibernate.Interceptor

org.hibernate.Interceptor
Allows user code to inspect and/or change property values. Inspection occurs before property values are written and after they are read from the database. There might be a single instance of Interceptor for a SessionFactory, or a new instance might be specified for each Session. Whichever approach is used, the interceptor must be serializable if the Session is to be serializable. This means that SessionFactory-scoped interceptors should implement readResolve(). The Session may not be invoked from a callback (nor may a callback cause a collection or proxy to be lazily initialized). Instead of implementing this interface directly, it is usually better to extend EmptyInterceptor and override only the callback methods of interest. @see SessionBuilder#interceptor(Interceptor) @see SharedSessionBuilder#interceptor() @see org.hibernate.cfg.Configuration#setInterceptor(Interceptor) @see EmptyInterceptor @author Gavin King
