All Implemented Interfaces:

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

public final class ScrapingInterceptor
extends Object
implements org.aopalliance.intercept.MethodInterceptor

Guice AOP interceptor responsible for taking action for method annotated with Scraping annotation. New scraping scope is created for each annotated method and is persistent until the end of invocation. Only ancestors of Harvester are applicable. An attempt to apply scraping scope to any other type will end up with thrown IllegalStateException. Just after the scope is created and shortly before it is left all registered ScrapingAware listeners are notified about the lifecycle change.
