Method Detail

### getIdentifier

    public java.lang.String getIdentifier()

  Get this server identifier.
  Returns:
    A String identifying this server context.

### errlog

    public void errlog(java.lang.String msg)

  Log an error into this server's error log.
  Parameters:
    `msg` - The message to log.

### log

    public void log(java.lang.String msg)

  Log a normal message into this server's log.
  Parameters:
    `msg` - The message to log.

### trace

    public void trace(java.lang.String msg)

  Emit a debugging trace on behalf of this server.
  Parameters:
    `msg` - The trace to emit.

### getInetAddress

    public java.net.InetAddress getInetAddress()

  Get the network addresses on which this server is listening.
  Returns:
    The InetAddress this server is listening to.

### getConfigResource

    public ResourceReference getConfigResource()

  Get the root, configuration resource for that server.
  Returns:
    A ContainerResource instance.

### clone

    public ServerHandler clone(ServerHandlerManager shm,
                               java.lang.String identifier,
                               ObservableProperties props)
                        throws ServerHandlerInitException

  Clone this server handler, and custmozie it with the given properties.

  Once cloned, the new server is assumed to be running happily, as if it had been initialized.

  Parameters:
    `shm` - The global server handler manager.
    `identifier` - The new ServerHandler identifier.
    `props` - The properties that overide part of the configuration of the cloned server.
  Returns:
    A newly created server, sharing the configuration of the cloned server, except for the config options defined by the given property set.
  Throws:
    ServerHandlerInitException - if initialization failed.

### initialize

    public void initialize(ServerHandlerManager shm,
                           java.lang.String id,
                           ObservableProperties props)
                    throws ServerHandlerInitException

  Initialize the server from the given set of properties. This method is called by the ServerManager instance, when launching the appropriate servers.

  A Server instance that has initialize itself successfully is considered to be running.

  Parameters:
    `shm` - The global server handler manager.
    `identifier` - A String identifying the server.
    `props` - The property set this server should use to initialize itself.
  Throws:
    ServerHandlerInitException - if initialization failed.

### shutdown

    public void shutdown()

  Shutdown this server handler. This is a synchronous method, that will return only once the server has been shutdown entirely (all the resources it uses have been released).

  This server handler clones are considered shutdown too.
