Constructor Detail

Sender

public Sender(Number160 peerId,
      List<PeerStatusListener> peerStatusListeners,
      ChannelClientConfiguration channelClientConfiguration,
      Dispatcher dispatcher,
      SendBehavior sendBehavior,
      PeerBean peerBean)

Creates a new sender with the listeners for offline peers.

Parameters:

peerStatusListeners - The listener for offline peers

channelClientConfiguration - The configuration used to get the signature factory

dispatcher -

concurrentHashMap -

Method Detail

channelClientConfiguration

public ChannelClientConfiguration channelClientConfiguration()

pingBuilderFactory

public PingBuilderFactory pingBuilderFactory()

pingBuilderFactory

public Sender pingBuilderFactory(PingBuilderFactory pingBuilderFactory)

sendTCP

public void sendTCP(io.netty.channel.SimpleChannelInboundHandler<Message> handler,
           FutureResponse futureResponse,
           Message message,
           ChannelCreator channelCreator,
           int idleTCPSeconds,
           int connectTimeoutMillis,
           PeerConnection peerConnection)

Send a message via TCP.

Parameters:

handler - The handler to deal with a reply message

futureResponse - The future to set the response

message - The message to send

channelCreator - The channel creator for the UPD channel

idleTCPSeconds - The idle time of a message until we fail

connectTimeoutMillis - The idle we set for the connection setup

sendSelf

public void sendSelf(FutureResponse futureResponse,
            Message message)

In case a message is sent to the sender itself, this is the cutoff.

Parameters:

futureResponse - the future to respond as soon as the proper handler returns it

message - the request

sendUDP

public void sendUDP(io.netty.channel.SimpleChannelInboundHandler<Message> handler,
           FutureResponse futureResponse,
           Message message,
           ChannelCreator channelCreator,
           int idleUDPSeconds,
           boolean broadcast)

Send a message via UDP.

Parameters:

handler - The handler to deal with a reply message

futureResponse - The future to set the response

message - The message to send

channelCreator - The channel creator for the UPD channel

idleUDPSeconds - The idle time of a message until we fail

broadcast - True to send via layer 2 broadcast

handleHolePunch

public void handleHolePunch(FutureResponse futureResponse,
                   Message message,
                   ChannelCreator channelCreator,
                   int idleUDPSeconds)

configureHandlers

public Map<String,Pair<io.netty.util.concurrent.EventExecutorGroup,io.netty.channel.ChannelHandler>> configureHandlers(io.netty.channel.SimpleChannelInboundHandler<Message> handler,
                                                                                                              FutureResponse futureResponse,
                                                                                                              int idleUDPSeconds,
                                                                                                              boolean isFireAndForget)

This method was extracted in order to avoid duplicate code in the HolePunchInitiator and in the initHolePunch(...) method.

Parameters:

handler -

futureResponse -

idleUDPSeconds -

isFireAndForget -

Returns:

handlers

afterConnect

public void afterConnect(FutureResponse futureResponse,
                Message message,
                io.netty.channel.ChannelFuture channelFuture,
                boolean fireAndForget)

After connecting, we check if the connect was successful.

Parameters:

futureResponse - The future to set the response

message - The message to send

channelFuture - the future of the connect

fireAndForget - True, if we don't expect a message

cachedRequests

public ConcurrentHashMap<Integer,FutureResponse> cachedRequests()

Get currently cached requests. They are cached because for example the receiver is behind a NAT. Instead of sending the message directly, a reverse connection is set up beforehand. After a successful connection establishment, the cached messages are sent through the direct channel.

peerStatusListeners

public List<PeerStatusListener> peerStatusListeners()
