Detailed Description

Drops all prims not under srcPrefix and moves those under srcPrefix to dstPrefix.

Data sources containing paths will be updated accordingly. That is, if it contains a path with srcPrefix as prefix, the prefix will be replaced by dstPrefix.

Note that this can be used as prefixing scene index by setting srcPrefix to the root path. It can also use to isolate part of the namespace by setting the srcPrefix and dstPrefix to be equal.

USDIMAGING_API SdfPathVector UsdImagingRerootingSceneIndex::GetChildPrimPaths ( const SdfPath primPath) const
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. The traveral is expected to give exactly the set of paths where prim exists as defined in GetPrim. The traversal is also 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.

USDIMAGING_API HdSceneIndexPrim UsdImagingRerootingSceneIndex::GetPrim ( const SdfPath primPath) const
overridevirtual

Returns a pair of (prim type, datasource). A prim exists at primPath if and only if datasource is a non-null pointer. In particular, we consider the prim to exist even if the prim type or the container that datasource points to is empty.

Note that we require GetChildPrimPaths to be consistent with this notion of prim existence. That is, unless primPath is the absolute root path, the prim at primPath exists if and only if primPath is contained in GetChildPrimPaths of the parent path.

This function is expected to be threadsafe.

Implements HdSceneIndexBase.
