Subject Re: [mina] Detecting connect failure without waiting for ConnectFuture
Date Fri, 11 Nov 2005 06:51:38 GMT
Since I badly needed to be able to detected connect failures without
having to wait for a ConnectFuture I added support for it. See the
attached patch. Basically what I've done is to add an extra callback to

void connectFailed( Throwable cause, Object mark ) throws Exception;

Then there is an extra connect-method in IoConnector:

ConnectFuture connect( SocketAddress address, SocketAddress localAddress,
                           IoHandler handler, Object mark ) throws

When connect fails for any of the IoConnector implementations they will
notify the IoHandler specified in the call to connect() and pass along
the mark Object. That's it.

NOTE: I had to move the call to sessionCreated in
DatagramConnectorDelegate.regsiterNew() down a bit to make it less
likely that sessionCreated() is called even if connect fails.

Is this something that could be considered for inclusion in Mina?
