Class InterceptedBeanProxyAdvice

java.lang.Object
  com.schlimm.springcdi.interceptor.processor.InterceptedBeanProxyAdvice

All Implemented Interfaces:

org.aopalliance.aop.Advice, org.aopalliance.intercept.Interceptor, org.aopalliance.intercept.MethodInterceptor

public class InterceptedBeanProxyAdvice
extends Object
implements org.aopalliance.intercept.MethodInterceptor

MethodInterceptor that is applied to any intercepted target bean. If a method call to the target bean is intercepted by user defined JSR 318 interceptors this advice creates a proxy for each target bean method that applies all the user defined JSR 318 interceptors. The method proxies are cached to maximize performance. Example: Bean ServiceImpl has a method called "sayHello()". The ServiceImpl has an InterceptorBinding declared that points to MyJSR318Interceptor. The the logic is as folows: The InterceptedBeanProxyAdvice is applied to ServiceImpl. If the sayHello() method is called the InterceptedBeanProxyAdvice creates a "method proxy", its target is ServiceImpl. The methid proxy applies the MyJSR318Interceptor advice. This logic is required 'cause every method on ServiceImple bean can have different interceptor chains, thus will have different method proxies that apply these chains.
