Package org.jcsp.net.tcpip
Class TCPIPNodeFactory
java.lang.Object
org.jcsp.net.tcpip.TCPIPNodeFactory
- All Implemented Interfaces:
Serializable
,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.

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
Connect to the named host on the default CNS port. If the server name is given asnull
then the CNS service will not be loaded.- Parameters:
cnsServer
- name of server
-
TCPIPNodeFactory
Connect to a named host on a specific port.- Parameters:
cnsServerAddress
- name of the servercnsServerPort
- port to connect to

Method Details
-
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. -
initNode
Initialise the node to listen on all local addresses, and start a CNS service.- Specified by:
initNode
in interfaceNodeFactory
- Parameters:
node
- the node to be initializedattribs
- access to the restricted node attributes- Throws:
NodeInitFailedException
- if a problem occurs
-
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
Sets the security service to be used.- Parameters:
security
- the new security authority.
