Sample text

This time, the method call returns with a poll object as soon as it dispatches the delegate with the call request, allowing the client to continue with its execution while remote object processes the query and produces a result. When a result is returned, the delegate thread retrieves it in the poll object, sets a flag in the object to indicate that it is available and notifies any thread blocked on the object. The resultAvailable() method of the poll object returns a boolean value and may be checked by the client to see if a result has arrived.

When the client issues such an invocation request, the call 28 O. Akın and N. Erdoğan returns back to the client immediately. The client does not get any acknowledgment from the remote object receiving the invocation. The client invokes asynchronously the log method of the remote object logger with the string parameter “my log message”. The call method returns right after dispatching the delegate with the call request. Thus, the client thread and the delegate thread run concurrently, the client returning back to its execution while the delegate blocked waiting for the call to return.

One contribution of this work is its use of run-time reflection to do the remote invocation, thus eliminating the need for any byte code adjustments or a new RMI preprocessor/compiler. Another contribution is the rich set of asynchronous call alternatives it provides the client with, which are accessible through an interface very similar to that of traditional RMI calls. As the framework is implemented on the client side and requires no modification on server code, it is easily integrated with existing server software.
