discoverAllFinished

public <L> void discoverAllFinished(InventoryEvent<L> event)

Description copied from interface: InventoryListener

Notifies the listener that the full discovery of resources has finished. The list in InventoryEvent.getPayload() is immutable and contains all resources discovered in breadth first order.

If the listener maintains a list of resources, this notification means that that the content of the old list should be thrown away and replaced by the list in InventoryEvent.getPayload().

Note that during full discovery #resourceAdded(InventoryEvent) is not invoked for resources delivered via InventoryListener.discoverAllFinished(InventoryEvent).

Specified by:

discoverAllFinished in interface InventoryListener

Parameters:

event - the InventoryEvent

resourcesAdded

public <L> void resourcesAdded(InventoryEvent<L> event)

Description copied from interface: InventoryListener

Notifies this listener that the resource in InventoryEvent.getPayload() was added to the monitored endpoint. Note that this event is fired only for resources added by the present agent. Resources added by other means can only be detected by a full discovery - see InventoryListener.discoverAllFinished(InventoryEvent).

Specified by:

resourcesAdded in interface InventoryListener

Parameters:

event - the InventoryEvent

resourceRemoved

public <L> void resourceRemoved(InventoryEvent<L> event)

Description copied from interface: InventoryListener

Notifies this listener that the resource in InventoryEvent.getPayload() was removed from the monitored endpoint. Note that this event is fired only for resources removed by the present agent. Resources removed by other means can only be detected by a full discovery - see InventoryListener.discoverAllFinished(InventoryEvent).

Specified by:

resourceRemoved in interface InventoryListener

Parameters:

event - the InventoryEvent
