Interface TcpChannel

All Superinterfaces:

AutoCloseable, Closeable, CloseableChannel

public interface TcpChannel
extends CloseableChannel

This is a tcp channel representing a single channel connection to another node. It is the base channel abstraction used by the TcpTransport and TransportService. All tcp transport implementations must return channels that adhere to the required method contracts.

Returns:

the local address of this channel.

getRemoteAddress

InetSocketAddress getRemoteAddress()

Returns the remote address for this channel. Can be null if channel does not have a remote address.

Returns:

the remote address of this channel.

sendMessage

void sendMessage(BytesReference reference,
                 ActionListener<Void> listener)

Sends a tcp message to the channel. The listener will be executed once the send process has been completed.

Parameters:

reference - to send to channel

listener - to execute upon send completion

addConnectListener

void addConnectListener(ActionListener<Void> listener)

Adds a listener that will be executed when the channel is connected. If the channel is still unconnected when this listener is added, the listener will be executed by the thread that eventually finishes the channel connection. If the channel is already connected when the listener is added the listener will immediately be executed by the thread that is attempting to add the listener.

Parameters:

listener - to be executed

getChannelStats

TcpChannel.ChannelStats getChannelStats()

Returns stats about this channel
