This method adds a listener to the diagnostics events

addModuleListener(String, String, ModuleListener)

This method adds a listener for a specific event on a specific listener.

eventHappenedFrom(DiagnosticModule)

This method is called by the DiagnosticsModules when an event occurs.

 public DiagnosticsServerImpl() throws RemoteException

This starts up the server

Throws: RemoteException

if anything fails in the communication

 public void addDiagnosticsListener(DiagnosticsListener listener) throws RemoteException

This method adds a listener to the diagnostics events

Parameters:

listener - the listener implementation

Throws: RemoteException

if anything fails in the communication

Throws: NoSuchModuleException

if there is no such module registered

Throws: NoSuchEventException

if there is no such event at that module

 public Vector getModuleList() throws RemoteException

This method returns the list of Modules (a vector of strings) registered with the diagnostics server.

Returns:

the list of modules registered with the DiagnosticsServer

Throws: RemoteException

if anything fails in the communication

 public DiagnosticModuleUI getModuleUI(String module) throws RemoteException, NoSuchModuleException

This method returns the UI for the given module name.

Parameters:

module - the module name

Returns:

the UI for that module

Throws: RemoteException

if anything fails in the communication

Throws: NoSuchModuleException

if there is no such module registered

 public void registerModule(DiagnosticModule module,
                            String name) throws NameConflictException

This method register the specified module with the server. Every DiagnosticModule should register himself with this server.

Parameters:

module - the specified module

name - the name with which to associate the module

 public synchronized void eventHappenedFrom(DiagnosticModule module)

This method is called by the DiagnosticsModules when an event occurs. This is the general notification to the server that just informs the world that the source (the module) has something to say.

 public boolean isAlive()

ping routine for the name service (required by Nameable interface)

 public static void main(String args[])

This main bootstraps the Diagnostics Server.
