Package org.springframework.orm.hibernate.support

Class ChainedInterceptorSupport

java.lang.Object

org.springframework.orm.hibernate.support.ChainedInterceptorSupport

All Implemented Interfaces:

org.hibernate.Interceptor

Direct Known Subclasses:

DependencyInjectionInterceptorFactoryBean.DependencyInjectionInterceptor, DirtiedHibernateSessionObjectRecorder, HibernateObjectsAuditInterceptor, OidGenerationInterceptor, ReadOnlyGetMethodEnforcer

public abstract class ChainedInterceptorSupport
extends Object
implements org.hibernate.Interceptor

Support class for Hibernate interceptors that participate in a chain. Suggested by Seth Ladd and based by code contributed by Oliver Hutchison. Necessary as Hibernate does not support native chaining of interceptors.
Implements all Interceptor methods as no ops. Abstract as it will do nothing unless a subclass overrides one or more methods. Any methods that are not handled by the subclass will delegate to the next interceptor in the chain.

1.2
