Subject [jira] Created: (DIRMINA-45) DemuxingProtocolCodecFactory.doDecode returns wrong value

DemuxingProtocolCodecFactory.doDecode returns wrong value
---------------------------------------------------------

         Key: DIRMINA-45
         URL: http://issues.apache.org/jira/browse/DIRMINA-45
     Project: Directory MINA
        Type: Bug
    Versions: 0.7.1    
 Environment: JDK1.4.2
    Reporter: Alex
 Assigned to: Trustin Lee 


I am not sure if it is a bug or I just misunderstood something.

I am implementing a protocol and use Demuxing* classes.
When I return MessageDecoder.OK from my MessageDecoder's decode method, MINA tries repeatedly
calls this method again. If I return MessageDecoder.NEED_DATA everything goes fine.
So, I would expect completely reversal behaviour.

I checked CumulativeProtocolDecoder and DemuxingProtocolCodecFactory classes.
In CumulativeProtocolDecoder.decode it says that doDecode is invoked repeatedly until it returns
false. Fine. But what "false" means here? I would guess that it means that buffer was completely
decoded and no more data is needed. But DemuxingProtocolCodedFactory.doDecode returns true
if decoder returned MessageDecoder.OK and false if decoder returned MessageDecoder.NEED_DATA.
Isn't wrong here?

Alex
