Method Details

getAdmin

public Admin getAdmin()

Description copied from interface: AdminAware

Returns the Admin associated with this element.

Specified by:

getAdmin in interface AdminAware

getVirtualMachineAdded

public VirtualMachineAddedEventManager getVirtualMachineAdded()

Description copied from interface: VirtualMachines

Returns the virtual machine added event manager allowing to add and remove VirtualMachineAddedEventListeners.

Specified by:

getVirtualMachineAdded in interface VirtualMachines

getVirtualMachineRemoved

public VirtualMachineRemovedEventManager getVirtualMachineRemoved()

Description copied from interface: VirtualMachines

Returns the virtual machine removed event manager allowing to add and remove VirtualMachineRemovedEventListeners.

Specified by:

getVirtualMachineRemoved in interface VirtualMachines

public VirtualMachinesStatisticsChangedEventManager getStatisticsChanged()

Description copied from interface: VirtualMachines

Returns a virtual machines statistics change event manager allowing to register for events of VirtualMachinesStatisticsChangedEvent.

Note, in order to receive events, the virtual machines need to be in a "statistics" monitored state.

Specified by:

getStatisticsChanged in interface VirtualMachines

getVirtualMachines

public VirtualMachine[] getVirtualMachines()

Description copied from interface: VirtualMachines

Returns the currently discovered virtual machines.

Specified by:

getVirtualMachines in interface VirtualMachines

iterator

public Iterator<VirtualMachine> iterator()

Specified by:

iterator in interface Iterable<VirtualMachine>
