Class IndexAndCacheAspect

java.lang.Object

com.erudika.para.server.aop.IndexAndCacheAspect

All Implemented Interfaces:

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

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

This is the core method interceptor which enables caching and indexing. It listens for calls to annotated DAO methods and adds searching and caching functionality to them. This technique allows us to control the caching and searching centrally for all implementations of the DAO interface.
