Constructor Detail

RoundRobinConnectionDistributor

public RoundRobinConnectionDistributor(NIOTransport transport)

RoundRobinConnectionDistributor

public RoundRobinConnectionDistributor(NIOTransport transport,
                                       boolean useDedicatedAcceptor)

RoundRobinConnectionDistributor

public RoundRobinConnectionDistributor(NIOTransport transport,
                                       boolean useDedicatedAcceptor,
                                       boolean isServerOnly)

Constructs RoundRobinConnectionDistributor with the given configuration.

Parameters:

transport -

useDedicatedAcceptor - depending on this flag server Connections, responsible for accepting client connections, will or will not use dedicated SelectorRunner

isServerOnly - true means this NIOChannelDistributor will be used by a Transport, which operates as a server only(the Transport will never initiate a client-side Connection). In this case we're able to use optimized (thread unsafe) distribution algorithm.

Method Detail

registerChannel

public void registerChannel(SelectableChannel channel,
                            int interestOps,
                            Object attachment)
                     throws IOException

Throws:

IOException

registerChannelAsync

public void registerChannelAsync(SelectableChannel channel,
                                 int interestOps,

                                        int interestOps,
                                        Object attachment,
