Class NioClient

    • Constructor Detail

      • NioClient

        public NioClient​(IpAddress bind_addr,
                         IpAddress server_addr)
        Creates an instance of an NioClient that acts as a client: no server channel is created and no acceptor is started to listen for incoming connections. Instead, a channel is created (bound to bind_addr/bind_port) and connected to server_addr/server_port. This is used to send messages to the remote server and receive messages from it. Note that there is only a single TCP connection established between the client and server.
        Parameters:
        bind_addr - The address to which the local channel should bind to. Can be null, then the OS picks the address
        server_addr - The address of the server to connect to
        Throws:
        java.lang.Exception - If the creation failed

                         int server_port)
        Creates an instance of an NioClient that acts as a client: no server channel is created and no acceptor is started to listen for incoming connections.

        Parameters:
        bind_addr - The address to which the local channel should bind to. Can be null, then the OS picks the address
        bind_port - The local port. Can be 0, then the OS picks the port.
        server_addr - The address of the server to connect to
        server_port - The port of the server to connect to.
        Throws:
