void UsdImagingSelectionSceneIndex::_PrimsAdded	(	const HdSceneIndexBase &	sender,
		const HdSceneIndexObserver::AddedPrimEntries &	entries
	)

overrideprotectedvirtual

Implements HdSingleInputFilteringSceneIndexBase.

void UsdImagingSelectionSceneIndex::_PrimsDirtied	(	const HdSceneIndexBase &	sender,
		const HdSceneIndexObserver::DirtiedPrimEntries &	entries
	)

overrideprotectedvirtual

Implements HdSingleInputFilteringSceneIndexBase.

overrideprotectedvirtual

Implements HdSingleInputFilteringSceneIndexBase.

USDIMAGING_API void UsdImagingSelectionSceneIndex::AddSelection ( const SdfPath & usdPath )

Given a path (including usd proxy path inside a native instance) of a USD prim, determine the corresponding prim in the Usd scene index (filtered by the UsdImagingNiPrototypePropagatingSceneIndex) and populate its selections data source.

USDIMAGING_API void UsdImagingSelectionSceneIndex::ClearSelection ( )

Reset the scene index selection state.

USDIMAGING_API SdfPathVector UsdImagingSelectionSceneIndex::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(); 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.

USDIMAGING_API HdSceneIndexPrim UsdImagingSelectionSceneIndex::GetPrim ( const SdfPath & primPath ) const

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.
