The

TraversalSpec

identified in a

SelectionSpec

reference must be within the same

PropertyFilterSpec

. Figure 1 shows the use of

SelectionSpec

references to a virtual machine

TraversalSpec

. The

SelectionSpec

references are associated with

Network

and

Datastore

traversals.

If the

ObjectSpec.selectSet

array contains a

SelectionSpec

, the referenced

TraversalSpec

must identify the same object type.

TraversalSpec.type

must match the type of the object specified in

ObjectSpec.obj

. The

PropertyCollector

applies the

TraversalSpec

to the object and uses the

TraversalSpec.path

property to extend its traversal.
