public class WatchServer

extends ApplicationActor

implements java.awt.event.ActionListener

The PaP Application class utilise the PaP Subscribe functionality to display log and status information for an existing operative DirectorActor. An instance of the class subscribe for all types of events that is reported to the subscription functionality, and this information is displayed in three different fields in a separate window. First, the log information as it occurs, then a list of actors that has been created after the WatchServer instance has been started, and last a list of Role Sessions that has been created after the WatchServer instance has been created. The WatchServer instance is terminated by pushing the X button in the window.

Method Detail

subscribeReport

public RequestResult subscribeReport(java.lang.String[] subscribeReport)
                              throws java.lang.Exception

Overrides:

subscribeReport in class ApplicationActor

Parameters:

subscribeReport - A list of reported events, where each event consist of four parameters: a) Event type is defined in SubscribeRequest class, b) Textual representation of the GAI address for the actor the report event concerns, c) Event type dependent information, and d) The point of time (in milliseconds since 1 jan. 1970) where the event was reported to the DirectorActor (Use DateFormat class for formatting to a suitable presentation format).

Returns:

Successful or failure in treatment of the results

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent e)

Specified by:

actionPerformed in interface java.awt.event.ActionListener

Parameters:

e - The reported action event. The action command skall be 'CancelEventInd'.

applicationActorEntry

public RequestResult applicationActorEntry(RequestPars pRP)
                                    throws java.lang.Exception

The common entry point for all external requests to the actor

Overrides:

applicationActorEntry in class ApplicationActor

Parameters:

pRP - The specification of request type and additional parameters

Returns:

Successful or failure indication

stateTransition

private RequestResult stateTransition(GAI sender,
                                      GAI receiver,
                                      ApplicationMessage am)
                               throws java.lang.Exception
