Class DelegatingIntroductionInterceptor

java.lang.Object
  org.springframework.aop.support.IntroductionInfoSupport
      org.springframework.aop.support.DelegatingIntroductionInterceptor

All Implemented Interfaces:: Serializable, Advice, Interceptor, MethodInterceptor, DynamicIntroductionAdvice, IntroductionInfo, IntroductionInterceptor

public class DelegatingIntroductionInterceptor
extends IntroductionInfoSupport
implements IntroductionInterceptor
extends IntroductionInfoSupport
implements IntroductionInterceptor

Convenient implementation of the 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.

A DelegatingIntroductionInterceptor is serializable if the delegate is.
