Class TCPIPNodeFactory

  • All Implemented Interfaces:
    Serializable, NodeFactory

    public class TCPIPNodeFactory
    extends Object
    implements NodeFactory

    Default factory for simple initialisations using the TCPIPv4 protocol package.

    Other constructors can be used to specify a particular CNS server. The default behaviour will extract a CNS server from the system property "org.jcsp.tcpip.DefaultCNSServer" with the server specified as a name or IP address with optional port number.

    If built with 1.4 or higher the user preferences will also be checked but only if a runtime supporting the preferences is available. If not present the system preferences will then be checked.

    • Constructor Detail

      • TCPIPNodeFactory

        public TCPIPNodeFactory()
        Default constructor, connecting to the local host on the default CNS port or to a host name in the system properties. The host name should be specified as name:port or just the host name to use the default CNS port.
      • TCPIPNodeFactory

        public TCPIPNodeFactory​(String cnsServer)
        Connect to the named host on the default CNS port. If the server name is given as null then the CNS service will not be loaded.
        Parameters:
        cnsServer - name of server
      • TCPIPNodeFactory

        public TCPIPNodeFactory​(String cnsServerAddress,
                                int cnsServerPort)
        Connect to a named host on a specific port.
        Parameters:
        cnsServerAddress - name of the server
        cnsServerPort - port to connect to
    • Method Detail

      • instantiate

        public static NodeFactory instantiate()
        Constructs an instance of this class. This method is provided so that a later implementation can opt to pass construction to an alternative under certain conditions. This is for use by the infrastructure only. Users should call the public constructors.
      • setLocalPort

        public void setLocalPort​(int port)
        Sets the port number that should be used. If this is not called then the system will allocate an arbitrary port.
        Parameters:
        port - the port number, 0 <= port < 65536.
      • setSecurityAuthority

        public void setSecurityAuthority​(SecurityService security)
        Sets the security service to be used.
        Parameters:
        security - the new security authority.
