Class HashMapCachingAdvisorChainFactory

java.lang.Object
  org.springframework.aop.framework.HashMapCachingAdvisorChainFactory

All Implemented Interfaces:

AdvisedSupportListener, AdvisorChainFactory

public final class HashMapCachingAdvisorChainFactory
extends Object
implements AdvisorChainFactory

AdvisorChainFactory implementation that caches by method.

Uses IdentityHashMap on JDK 1.4+ or Commons Collections 3.x IdentityMap (if available), which skip expensive Method.hashCode() calls. Falls back to standard HashMap on plain JDK 1.3.

Method Summary

void	activated(AdvisedSupport advisedSupport) Invoked when the first proxy is created.
void	adviceChanged(AdvisedSupport advisedSupport) Invoked when advice is changed after a proxy is created.
List	getInterceptorsAndDynamicInterceptionAdvice(Advised config, Object proxy, Method method, Class targetClass) Determine a list of MethodInterceptor and InterceptorAndDynamicMethodMatcher elements (using the latter if there is a dynamic method matcher that needs evaluation at runtime)
