Constructor Details

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.
