Base class for implementing scene indices which read from and write to only material network data sources.
Subclasses implement only _GetFilteringFunction to provide a callback to run when a material network is first queried.

finaloverridevirtual |
Returns the paths of all scene index prims located immediately below primPath.
This function can be used to traverse the scene by recursing from SdfPath::AbsoluteRootPath(); such a traversal is expected to give the same set of prims as the flattening of the scene index's PrimsAdded and PrimsRemoved messages. This function is expected to be threadsafe.
Implements HdSceneIndexBase.

finaloverridevirtual |
Returns a pair of (prim type, datasource) for the object at primPath.
If no such object exists, the type will be the empty token and the datasource will be null. This function is expected to be threadsafe.
Implements HdSceneIndexBase.
