typedef void(* | UniqueChangedFuncPtr) (TfRefBase const *, bool) |
Transfers primvars present on the locally bound material.
Any matching primvar already present will have a stronger opinion.
As it's expected that primvars inherited by the destination location should have a stronger opinion than those transfered here, inherited primvars must be flattened in advance of this scene index.
This is in support of shading workflows.
This also declares dependencies to ensure invalidation if a HdDependencyForwardingSceneIndex is present downstream. (Because those dependencies are computed on demand, no meaningful additional work is done otherwise.)

overridevirtual |
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.

overridevirtual |
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.
