Class DelegatePerTargetObjectIntroductionInterceptor

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

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

public class DelegatePerTargetObjectIntroductionInterceptor
extends IntroductionInfoSupport
implements IntroductionInterceptor
extends IntroductionInfoSupport
implements IntroductionInterceptor

Convenient implementation of the IntroductionInterceptor interface.

This differs from DelegatingIntroductionInterceptor in that a single instance of this class can be used to advise multiple target objects, and each target object will have its own delegate (whereas DelegatingIntroductionInterceptor shares the same delegate, and hence the same state across all targets).

The suppressInterface method can be used to suppress interfaces implemented by the delegate class but which should not be introduced to the owning AOP proxy.

An instance of this class is serializable if the delegates are.

Note: There are some implementation similarities between this class and DelegatingIntroductionInterceptor that suggest a possible refactoring to extract a common ancestor class in the future.
