Annotation Type Asynchronous

@Documented @Target(METHOD) @Retention(RUNTIME) public @interface Asynchronous
Used on a method in a remotable exported interface to designate that the call is made asynchronously. The call will be issued, but the caller will return without waiting for the return value to come back from the other side. The signature of the method must return void.
 interface Foo {
     void bar();
     void zot();

 Foo foo = getSomeRemoteReferenceToFoo();
 // this invocation calls a remote method, wait for that to complete,
 // then return.;
 // this invocation returns immediately after the request to execute a remote method
 // is sent to the other side. There's no ordering guarantee as to when
 // this method actually gets executed. For example, if you invoke two async
 // calls, they may execute in the reverse order.
