New feature in 2.0: Request-Response Filter

Hi folks,

Today, I added a new feature to the trunk.  The issue has been filed
since the early days of MINA, but we didn't give it high priority
because it was a good-to-have feature.  I apologize those who wait for
this issue to be resolved for a long time.

The Request-Response filter is very useful for a client application
that deals with a request-response protocol.  Please refer to my last
comment of the following JIRA page for the detailed explanation and
example:

https://issues.apache.org/jira/browse/DIRMINA-92#action_12488311

Any questions and additional feature request on this filter are welcome.

They were added since JDK 1.6.  I made it backward-compatible now.
Thanks for the heads up!

Hi Trustin,

Just updated my working trunk and I noticed a problem with the feature 
you just added.

The class RequestTimeoutException extends IOException and tries to call 
the superclass constructor with inappropriate arguments. (IOException 
has a paramaterless constructor and one that accepts a string.)

 public RequestTimeoutException(Request request, String message, 
Throwable cause) {
        super(message, cause);
       ...

 public RequestTimeoutException(Request request, Throwable cause) {
        super(cause);
      ...

cheers,
John

BTW - Those are some very beautiful wedding photos.  Hearty 
congratulations.

Re: New feature in 2.0: Request-Response Filter

Hi folks,

Until now I had only implemented server apps with MINA (IoAcceptor), and no
client apps (IoConnector).

I started working on a small tutorial about ProtocolDecoder/ProtocolEncoder
to complement Mark's Getting Started Guide,
and while implementing the client side I was wondering if a ReadFuture would
be an interesting feauture.

Suppose you have a request-response protocol and you want to implement the
client synchronously:
connect, send a request and wait until the response comes in.

What is currently the best way to go ?

With a ReadFuture it could be done like this:

    Object request = ...;
    ConnectFuture connectFuture = connector.connect(new
InetSocketAddress("localhost",5555));
    connectFuture.join(100);
    if (connectFuture.isConnected()) {
      IoSession session = connectFuture.getSession();
      session.write( request );
      ReadFuture readFuture = session.read();
      readFuture.join();
      if (readFuture.messageRead()) {
        Object response = readFuture.getResult();
        doSomethingWith(response);
      }
      session.close().join();
    }

What do you think ?

Maarten
