Examples of handleTopologyEvent()

org.apache.sling.discovery.TopologyEventListener.handleTopologyEvent()

Inform the service about an event in the topology - or in the discovery of the topology.

The TopologyEvent contains details about what changed. The supported event types are:

TOPOLOGY_INIT sent when the TopologyEventListener was first bound to the discovery service - represents the initial state of the topology at that time.
TOPOLOGY_CHANGING sent when the discovery service discovered a change in the topology and has started to settle the change. This event is sent before TOPOLOGY_CHANGED but is optional
TOPOLOGY_CHANGED sent when the discovery service discovered a change in the topology and has settled it.
PROPERTIES_CHANGED sent when the one or many properties have changed in an instance in the current topology

A note on instance restarts: it is currently not a requirement on the discovery service to send a TopologyEvent should an instance restart occur rapidly (ie within the change detection timeout). A TopologyEvent is only sent if the number of instances or any property changes. Should there be a requirement to detect a restart in a guaranteed fashion, it is always possible to set a particular property (using the PropertyProvider) to the instance start time and have others detect a change in that property. @param event The topology event
