  • Method Details

    • acceptFailed

      public void acceptFailed(IOException exception)
      Description copied from interface: ServerSocketObserver
      Called by the NIOService on the NIO thread when an accept fails on the socket.

      Note: Since this is a direct callback on the NIO thread, this method will suspend IO on all other connections until the method returns. It is therefore strongly recommended that the implementation of this method returns as quickly as possible to avoid blocking IO.

      Specified by:
      acceptFailed in interface ServerSocketObserver
      Parameters:
      exception - the reason for the failure, never null.
    • serverSocketDied

      public void serverSocketDied(Exception exception)
      Description copied from interface: ServerSocketObserver
      Called by the NIOService on the NIO thread when the server socket is closed.

      Note: Since this is a direct callback on the NIO thread, this method will suspend IO on all other connections until the method returns. It is therefore strongly recommended that the implementation of this method returns as quickly as possible to avoid blocking IO.

      Specified by:
      serverSocketDied in interface ServerSocketObserver
      Parameters:
      exception - the exception that caused the close, or null if this was caused by an explicit close() on the NIOServerSocket.
    • newConnection

      public void newConnection(NIOSocket nioSocket)
      Description copied from interface: ServerSocketObserver
      Called by the NIOService on the NIO thread when a new connection has been accepted by the socket.

      The normal behaviour would be for the observer to assign a reader and a writer to the socket, and then finally invoke NIOSocket#listen(SocketObserver) on the socket.

      Note: Since this is a direct callback on the NIO thread, this method will suspend IO on all other connections until the method returns. It is therefore strongly recommended that the implementation of this method returns as quickly as possible to avoid blocking IO.

      Specified by:
      newConnection in interface ServerSocketObserver
      Parameters:
      nioSocket - the socket that was accepted.
    • broadcast

      public void broadcast(naga.examples.ChatServer.User sender, String string)
    • main

      public static void main(String... args)
      Runs the echo server.
      Parameters:
      args - command line arguments, assumed to be a 1 length string containing a port.
    • getEventMachine

      public EventMachine getEventMachine()
