Constructor Detail

PerformanceData

public PerformanceData(VirtualSessionManager vsm)

Creates the performance data panel and handles it. This should be created from the Server Administration GUI.

Method Detail

onSlavePerformanceData

public static void onSlavePerformanceData(String slave,
                                          Transaction trans)

The load balancer calls this method when it receives a transaction from a slave server.

onPerformanceDataRequest

public static Transaction onPerformanceDataRequest(int waitTime)

This server (a slave) is instructed to create a performance data transaction and return it.

onSlaveDisconnected

public static void onSlaveDisconnected(String slave)

The load balancer calls this method when a slave "drops" out from the controller.

onPanelCreate

public void onPanelCreate(VirtualPanel vp)

Called to initialize the panel before it is displayed.

Specified by:

onPanelCreate in interface VirtualPanelListener

Overrides:

onPanelCreate in class VirtualPanelAdapter

Parameters:

vp - The panel issuing the event.

onPanelClosing

public boolean onPanelClosing(VirtualPanel vp)

Called when the close button of a panel is pressed, but before any other processing has been done. If this function returns false, the application close object will be called (if defined), otherwise a faked keypress of the Escape key is performed. If these two actions failed (because there is no close object or no button or menu item is connected to the Escape key), then the function onPanelClose is called.

Specified by:

onPanelClosing in interface VirtualPanelListener

Overrides:

onPanelClosing in class VirtualPanelAdapter

Parameters:

vp - The panel issuing the event.

Returns:

true to cancel all default processing.

See Also:

VirtualPanelListener.onPanelClose(se.entra.phantom.server.VirtualPanel)

onPanelClose

public boolean onPanelClose(VirtualPanel vp)

Called when the close button of a panel is pressed. When a panel has a listener attached to it, it will not perform default close operations. The listener should dismiss or destroy the panel unless cancelling of the panel is not permitted.

Specified by:

onPanelClose in interface VirtualPanelListener

Overrides:

onPanelClose in class VirtualPanelAdapter

Parameters:

vp - The panel issuing the event.

Returns:

false to proceed with default processing, true to indicate alternate processing.

See Also:

VirtualPanelListener.onPanelClosing(se.entra.phantom.server.VirtualPanel)

onPanelDestroy

public void onPanelDestroy(VirtualPanel vp)

Called to inform the listener that the panel is destroyed.

Specified by:

onPanelDestroy in interface VirtualPanelListener

Overrides:

onPanelDestroy in class VirtualPanelAdapter

Parameters:

vp - The panel issuing the event.

onAction

public void onAction(VirtualPanel vp,
                     String controlID)

Push buttons and menu items (or pop-up menu items) generates this event when selected and the original onAction wasn't processed.

Overrides:

onAction in class VirtualComponentAdapter

Parameters:

vp - The panel issuing the event, parent of the control.

controlID - The control ID issuing the event.

run

public void run()

Performs the performance data gathering.

Specified by:

run in interface Runnable
