Method Detail

main

public static void main(java.lang.String[] args)

Run a simple version of the GUI by starting a single connection which will populate a single topology drawn by a PZLayoutManager.

makeDefaultConnection

public static ConnectionHandler makeDefaultConnection(PZManager manager,
                                                      java.lang.String server,
                                                      java.lang.Short port,
                                                      boolean subscribeSwitches,
                                                      boolean subscribeLinks)

Creates a connection which will populate a new topology.

Parameters:

manager - the manager of the GUI elements

server - the IP or hostname where the back-end is located

port - the port the back-end is listening on

subscribeSwitches - whether to subscribe to switch changes

subscribeLinks - whether to subscribe to link changes

getServer

public static Pair<java.lang.String,java.lang.Short> getServer(java.lang.String[] args)

Gets the IP[:PORT] to connect to.

Parameters:

args - the command-line arguments to extract a server from; if one is not provided then the user will be prompted for one

Returns:

the server to connect to

getServers

public static java.util.ArrayList<Pair<java.lang.String,java.lang.Short>> getServers(java.lang.String[] args)

Gets the IP[:PORT](s) to connect to. If no servers are specified, the user is prompted to specify one. If the user does not specify anything when prompted, then the program terminates.

Parameters:

args - the command-line arguments to extract server(s) from; if none are provided then the user will be prompted for one

Returns:

the server to connect to

parseServerIdentifier

public static Pair<java.lang.String,java.lang.Short> parseServerIdentifier(java.lang.String s)

Returns the parse of a IP[:PORT]. If PORT is omitted, the Options.DEFAULT_PORT is returned for the port value.

Returns:

IP-port pair

promptForServer

public static Pair<java.lang.String,java.lang.Short> promptForServer()

Ask the user for the backend's IP[:PORT] in dialog box.
