Interface MethodInterceptor

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface MethodInterceptor

Provides method interception such that logic can be provided both before and after method invocation.

MethodInterceptor instances are provided by AspectProvider.interceptor(Method, Annotation).

Method Summary

Modifier and Type	Method	Description
void	invoke(Invocation invocation)	Implementation can perform before and after invocation logic.

Method Details

invoke

void invoke(Invocation invocation)
     throws Throwable

Implementation can perform before and after invocation logic.

If a method interceptor wants to replace the result it does this via Invocation.result(Object). This is a little different to traditional method interceptors (i.e. org.org.aopalliance.intercept.MethodInterceptor). It is done this way to handle implied generic return types in the generated source code.

Parameters:

invocation - The invocation being intercepted

Throws:

Throwable - If the interception or underlying invocation throws an exception
