Examples of org.springframework.aop.support.DelegatingIntroductionInterceptor

org.springframework.aop.support.DelegatingIntroductionInterceptor
Convenient implementation of the {@link org.springframework.aop.IntroductionInterceptor} interface.
Subclasses merely need to extend this class and implement the interfaces to be introduced themselves. In this case the delegate is the subclass instance itself. Alternatively a separate delegate may implement the interface, and be set via the delegate bean property.
Delegates or subclasses may implement any number of interfaces. All interfaces except IntroductionInterceptor are picked up from the subclass or delegate by default.
The suppressInterface method can be used to suppress interfaces implemented by the delegate but which should not be introduced to the owning AOP proxy.
An instance of this class is serializable if the delegate is. @author Rod Johnson @author Juergen Hoeller @since 16.11.2003 @see #suppressInterface @see DelegatePerTargetObjectIntroductionInterceptor
