Examples of programming5.net.sockets.TCPClient$TCPReceiver

programming5.net.NetworkException
This class is the TCP socket implementation of a MessagingClient. Can be used to handle several TCP connections. Messages will be sent to all open connections if no address is specified (messages sent to a specific address will create connections that remain open until the object is terminated and all connections are closed), and will be received from any connection indistinguishably. If incoming messages need to be distinguished by origin, separate TCPClient objects should be used for each one. @see programming5.net.MessagingClient @see programming5.net.PluggableClient @see java.net.Socket @author Andres Quiroz Hernandez @version 6.09
