All Implemented Interfaces:

MonitoredVm, BufferedMonitoredVm

public class FileMonitoredVm
extends AbstractMonitoredVm

Concrete implementation of the AbstractMonitoredVm class for the file: protocol for the HotSpot PerfData monitoring implementation.

addVmListener in class AbstractMonitoredVm

Parameters:

l - the VmListener to add.

removeVmListener

public void removeVmListener(VmListener l)

Remove a VmListener. The given listener is removed from the list of VmListener objects to be notified of MonitoredVm related events..
