beforeInvoke

public Object beforeInvoke(Object object,

Specified by:

beforeInvoke in interface Interceptor

Parameters:

object - receiver object for the method call

methodName - name of the method to call

arguments - arguments to the method call

Returns:

any arbitrary result that replaces the result of the original method call only if doInvoke() returns false and afterInvoke() relays this result.

afterInvoke

public Object afterInvoke(Object object,
                          String methodName,
                          Object[] arguments,
