org.springframework.aop.framework: public final class: HashMapCachingAdvisorChainFactory

org.springframework.aop.framework
public final class: HashMapCachingAdvisorChainFactory [javadoc | source]

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

All Implemented Interfaces:
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.
