Class PipelineConnectionBase.ResponseHandler

java.lang.Object

org.jredis.ri.alphazero.connection.PipelineConnectionBase.ResponseHandler

All Implemented Interfaces:

java.lang.Runnable, Connection.Listener

Enclosing class:

PipelineConnectionBase

public final class PipelineConnectionBase.ResponseHandler
extends java.lang.Object
implements java.lang.Runnable, Connection.Listener

Provides the response processing logic as a Runnable.

TODD: Needs to have a more regulated operating cycle. Right now its just infinite loop until something goes boom. Not good.

Since:

alpha.0

Version:

alpha.0, Oct 18, 2009

ResponseHandler

public ResponseHandler()

Adds self to the listeners of the enclosing Connection instance.

Method Detail

run

public void run()

Keeps processing the PendingRequests in the pending Queue until a QUIT is encountered in the pending queue. Thread will stop after processing the QUIT response (which is expected to be a VirtualResponse.

TODO: not entirely clear what is the best way to handle exceptions.

TODO: socket Reconnect in the context of pipelining is non-trivial, and maybe not even practically possible. (e.g. request n is sent but pipe breaks on some m (m!=n) response. non trivial. Perhaps its best to assume broken connection means faulted server, specially given the fact that a pipeline has a heartbeat so the issue can not be timeout.
