ConfigHandler
public ConfigHandler(AbstractEndpoint endpoint, com.lmax.disruptor.EventSink<ResponseEvent> responseBuffer, boolean isTransient, boolean pipeline)
Creates a newConfigHandler
with the default queue for requests.- Parameters:
endpoint
- theAbstractEndpoint
to coordinate with.responseBuffer
- theRingBuffer
to push responses into.

Method Detail
-
encodeRequest
protected HttpRequest encodeRequest(ChannelHandlerContext ctx, ConfigRequest msg) throws Exception
Description copied from class: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.- Specified by:
encodeRequest
in classAbstractGenericHandler<HttpObject,HttpRequest,ConfigRequest>
- Parameters:
ctx
- the context passed in.msg
- the outgoing message.- Returns:
- the encoded request.
- Throws:
Exception
- as a generic error.
-
decodeResponse
protected CouchbaseResponse decodeResponse(ChannelHandlerContext ctx, HttpObject msg) throws Exception
Description copied from class:AbstractGenericHandler
Decodes the incoming response and transforms it into aCouchbaseResponse
. Note that the actual notification is handled by this generic handler, the implementing class only is concerned about the conversion itself.- Specified by:
decodeResponse
in classAbstractGenericHandler<HttpObject,HttpRequest,ConfigRequest>
- Parameters:
ctx
- the context passed in.msg
- the incoming message.- Returns:
- a response or null if nothing should be returned.
- Throws:
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.
-
finishedDecoding
protected void finishedDecoding()
Description copied from class:AbstractGenericHandler
Notify that decoding is finished. This needs to be called by the child handlers in order to signal that operations are done.- Overrides:
finishedDecoding
in classAbstractGenericHandler<HttpObject,HttpRequest,ConfigRequest>
-
handlerRemoved
public void handlerRemoved(ChannelHandlerContext ctx) throws Exception
- Specified by:
handlerRemoved
in interfaceChannelHandler
- Overrides:
handlerRemoved
in classAbstractGenericHandler<HttpObject,HttpRequest,ConfigRequest>
- Throws:
Exception
-
serviceType
protected ServiceType serviceType()
Description copied from class:AbstractGenericHandler
Returns theServiceType
associated with this handler.- Specified by:
serviceType
in classAbstractGenericHandler<HttpObject,HttpRequest,ConfigRequest>
- Returns:
- the service type.
