public ConfigHandler(AbstractEndpoint endpoint, com.lmax.disruptor.EventSink<ResponseEvent> responseBuffer, boolean isTransient)
Creates a new ConfigHandler
with the default queue for requests.
endpoint
- the AbstractEndpoint
to coordinate with.responseBuffer
- the RingBuffer
to push responses into.protected HttpRequest encodeRequest(ChannelHandlerContext ctx, ConfigRequest msg) throws Exception
AbstractGenericHandler
Encode the outgoing request and return it in encoded format.
This method needs to be implemented by the child handler and is responsible for the actual conversion.
encodeRequest
in class AbstractGenericHandler<HttpObject,HttpRequest,ConfigRequest>
ctx
- the context passed in.msg
- the outgoing message.Exception
- as a generic error.protected CouchbaseResponse decodeResponse(ChannelHandlerContext ctx, HttpObject msg) throws Exception
AbstractGenericHandler
Decodes the incoming response and transforms it into a CouchbaseResponse
.
Note that the actual notification is handled by this generic handler, the implementing class only is concerned about the conversion itself.

ctx
- the context passed in.msg
- the incoming message.Exception
- as a generic error. It will be bubbled up to the user (wrapped in a CouchbaseException) in the onError of the request’s Observable.protected void finishedDecoding()
AbstractGenericHandler
Notify that decoding is finished. This needs to be called by the child handlers in order to signal that operations are done.
