Method Detail

invoke

public final Object invoke(Object proxy,
                           Method invoked,
                           @Nullable

                    throws Throwable

• proxy.hashCode() delegates to AbstractInvocationHandler#hashCode
• proxy.toString() delegates to AbstractInvocationHandler#toString
• proxy.equals(argument) returns true if:
  • proxy and argument are of the same type
  • and AbstractInvocationHandler#equals returns true for the InvocationHandler of argument
• other method calls are dispatched to #handleInvocation.

Specified by:

invoke in interface InvocationHandler
