Class NettyUDPMessageSender

java.lang.Object

io.nadron.communication.NettyUDPMessageSender

All Implemented Interfaces:

MessageSender, MessageSender.Fast

public class NettyUDPMessageSender
extends Object
implements MessageSender.Fast

Description copied from interface: MessageSender

Since message sender would have a network connection, it would require some cleanup. This method can be overriden to close underlying channels and so on.

Specified by:

close in interface MessageSender

getRemoteAddress

public SocketAddress getRemoteAddress()

getChannel

public io.netty.channel.socket.DatagramChannel getChannel()

toString

public String toString()

Overrides:
