java.lang.Object org.springframework.aop.framework.ReflectiveMethodInvocation
public class ReflectiveMethodInvocation
Spring's implementation of the AOP Alliance
MethodInvocation
interface,
implementing the extended
ProxyMethodInvocation
interface.
Invokes the target object using reflection. Subclasses can override the
invokeJoinpoint()
method to change this behavior, so this is also
a useful base class for more specialized MethodInvocation implementations.
It is possible to clone an invocation, to invoke proceed()
repeatedly (once per clone), using the invocableClone()
method.
It is also possible to attach custom attributes to the invocation,
using the setUserAttribute(java.lang.String, java.lang.Object)
/ getUserAttribute(java.lang.String)
methods.

public ReflectiveMethodInvocation(Object proxy, Object target, Method method, Object[] arguments, Class targetClass, List interceptorsAndDynamicMethodMatchers)
proxy
- the proxy object that the invocation was made ontarget
- the target object to invokemethod
- the method to invokearguments
- the arguments to invoke the method withtargetClass
- the target class, for MethodMatcher invocationsinterceptorsAndDynamicMethodMatchers
- interceptors that should be applied,
along with any InterceptorAndDynamicMethodMatchers that need evaluation at runtime.
MethodMatchers included in this struct must already have been found to have matched
as far as was possibly statically. Passing an array might be about 10% faster,
but would complicate the code. And it would work only for static pointcuts.Method Detail |

We want a shallow copy in this case: We want to use the same interceptor chain and other object references, but we want an independent value for the current interceptor index.
