public class ReflectiveMethodInvocation extends Object implements ProxyMethodInvocation, Cloneable
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.
NOTE: This class is considered internal and should not be
directly accessed. The sole reason for it being public is compatibility
with existing framework integrations (e.g. Pitchfork). For any other
purposes, use the ProxyMethodInvocation interface instead.

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.public final Object getProxy()
