public AbstractMonitorView()

Method Detail

getPanel

public JComponent getPanel()

Description copied from interface: MonitorView

Returns the graphical component maintained by this view.

Specified by:

getPanel in interface MonitorView

Returns:

Graphical component to be displayed by the GUI.

getFilter

public AgentChannelsFilter getFilter()

Specified by:

getFilter in interface MonitorView

setFilter

public void setFilter(AgentChannelsFilter filter)

Specified by:

setFilter in interface MonitorView

isChannelListFixed

protected boolean isChannelListFixed()

connect

public void connect(AgentStatusEvent event)

Description copied from interface: AgentStatusListener

Called when a new agent connects to the buses. Newly registered listeners are notified immediately if the agent is already connected.

The event passed to this method does not contain any information on channels (corresponding methods return empty collections) or a reference to a status message. The event can only be used to retrieve AgentInfo descriptor and a reference to the AgentStatusAggregator instance.

The implementation should return quickly. Any blocking operations should be scheduled on a separate thread.

Specified by:

connect in interface AgentStatusListener

Parameters:

event - Event.

configure

public void configure(AgentStatusEvent event)

Description copied from interface: AgentStatusListener

Called when the complete static information on the source agent (including channels dictionary) becomes available for the first time, and when it changes. Newly registered listeners are notified immediately if the information is already available.

The event passed to this method contains a list of added channels. Methods accessing lists of changed and removed channels will return empty collections. Since the configuration event is not triggered by a status message, getMessage() method returns null.

Specified by:

configure in interface AgentStatusListener

Parameters:

event - Event.

statusChanged

public void statusChanged(AgentStatusEvent event)

Description copied from interface: AgentStatusListener

Called on status change.

Specified by:

statusChanged in interface AgentStatusListener

Parameters:

event - event Event.

disconnect

public void disconnect(AgentStatusEvent event)

Description copied from interface: AgentStatusListener

Called when an agent disconnects from the buses or goes into OFFLINE state.

The event passed to this method does not contain any information on channels status - corresponding methods return empty collections. Since the disconnection event might or might not be triggered by a status message, getMessage() method might return null.

The implementation should return quickly. Any blocking operations should be scheduled on a separate thread.

Specified by:

disconnect in interface AgentStatusListener

Parameters:

event - Event.

connect

protected void connect(org.lsst.ccs.bus.data.AgentInfo agent)

disconnect

protected void disconnect(org.lsst.ccs.bus.data.AgentInfo agent)

addChannels

protected void addChannels(org.lsst.ccs.bus.data.AgentInfo agent,
                           Map<String,AgentChannel> channels)

Adds channels to display.

Parameters:

agent - Source agent.

channels - Map of paths to channels.

removeChannels

protected void removeChannels(org.lsst.ccs.bus.data.AgentInfo agent,
                              List<String> paths)

Removes a channels from this view.

Parameters:

agent - Source agent.

paths - Paths to remove.

updateChannels

protected void updateChannels(org.lsst.ccs.bus.data.AgentInfo agent,
                              Map<String,Map.Entry<AgentChannel,List<String>>> channels)

Called to notify this view that the specified channels have been updated.

Parameters:

agent - Source agent.

channels - Map of paths to key-value pairs, where the key is as AgentChannel object and the value is a list of changed attributes.

sendCommand

protected final Object sendCommand(Duration timeout,
                                   String dest,
                                   String target,
                                   String cmnd,
                                   Object... args)
                            throws Exception

Throws:

Exception

sendCommand

protected final void sendCommand(String dest,
                                 String target,
