Package org.springframework.aop.framework.adapter

Class ThrowsAdviceInterceptor

java.lang.Object
org.springframework.aop.framework.adapter.ThrowsAdviceInterceptor
All Implemented Interfaces:
Advice, Interceptor, MethodInterceptor, AfterAdvice
public class ThrowsAdviceInterceptor extends Object implements MethodInterceptor, AfterAdvice
Interceptor to wrap an after-throwing advice.

The signatures on handler methods on the ThrowsAdvice implementation method argument must be of the form:
void afterThrowing([Method, args, target], ThrowableSubclass);

Only the last argument is required.

Some examples of valid methods would be: 

public void afterThrowing(Exception ex)
public void afterThrowing(RemoteException)
public void afterThrowing(Method method, Object[] args, Object target, Exception ex)
public void afterThrowing(Method method, Object[] args, Object target, ServletException ex)

This is a framework class that need not be used directly by Spring users.
