Specified by:

resourcesRemoved in interface InventoryListener

Parameters:

event - the InventoryEvent

discoveryCompleted

public <L> void discoveryCompleted(DiscoveryEvent<L> event)

Specified by:

discoveryCompleted in interface InventoryListener

Parameters:

event - the DiscoveryEvent

unschedule

public <L> void unschedule(SamplingService<L> service,
                           Collection<Resource<L>> resources)
