Constructor Detail

MmPanel

public MmPanel()

Creates MmPanel with default memory monitor for local VM.

MmPanel

public MmPanel(MemoryMonitor monitor)

Creates MmPanel with specified memory monitor. The new instance will join to the group of given monitor.

Method Detail

setMode

public void setMode(int mode)

Sets visual mode (for example, BAR_HISTORY_MODE).

setInfoPanelVisible

public void setInfoPanelVisible(boolean visible)

Sets visibility of InfoPanel.

resultReceived

public void resultReceived(long totalMemory,
                           long freeMemory)

This method will be invoked by host monitor, when monitoring result received.

Specified by:

resultReceived in interface Subscriber

Parameters:

totalMemory - total allocated memory.

freeMemory - free memory.

hostStopped

public void hostStopped()

This method will be invoked by host monitor, when host monitor stopped.

Specified by:

hostStopped in interface Subscriber

clearHistory

public void clearHistory()

Clears history graph.

getMonitor

public MemoryMonitor getMonitor()

Returns internal monitor.

messageDelivered

public void messageDelivered(java.lang.String message)

This method will be executed when message delivered from host. By default, it does nothing. If you want to do something useful, set MessageHandler (see also the setMessageHandler() method).

Specified by:

messageDelivered in interface Subscriber

Parameters:

message - User message.

See Also:

Subscriber.messageDelivered(String), setMessageHandler(MessageHandler)

setMessageHandler

public void setMessageHandler(MessageHandler handler)
