org.apache.sling.discovery.InstanceDescription
An InstanceDescription represents and contains information about an instance that is part of a TopologyView.
Note that all methods are idempotent - they always return the same values on subsequent calls. Rather, on any change new InstanceDescriptions are created. @see TopologyView
