Detailed Description

A datasource representing structured (named, hierarchical) data, for example a geometric primitive or a sub-object like a material definition. Note that implementations are responsible for providing cache invalidation, if necessary.

Member Function Documentation

virtual HdDataSourceBaseHandle HdContainerDataSource::Get ( const TfToken &  name )

pure virtual

Returns the child datasource of the given name. This call is expected to be threadsafe.

Implemented in UsdImagingDataSourcePrim, UsdImagingDataSourceDataSharing, UsdImagingDataSourcePrimOrigin, UsdImagingDataSourceXform, UsdImagingDataSourceExtentsHint, HdsiLocatorCachingSceneIndex::_DataSource, UsdImagingDataSourceExtent, UsdImagingDataSourceMapped, UsdImagingDataSourceRenderVarPrim, UsdImagingDataSourcePrimvar, UsdImagingDataSourceMeshPrim, UsdImagingDataSourceRenderProductPrim, UsdImagingDataSourcePointInstancerPrim, UsdImagingDataSourceTetMeshPrim, UsdImagingDataSourceBasisCurvesPrim, UsdImagingDataSourceMesh, UsdImagingDataSourcePurpose, UsdImagingDataSourceMaterialPrim, UsdImagingDataSourcePointInstancerTopology, UsdSkelImagingDataSourceResolvedPointsBasedPrim, UsdImagingDataSourceRenderSettingsPrim, UsdImagingDataSourceFieldAssetPrim, UsdImagingDataSourceCustomPrimvars, HdOverlayContainerDataSource, HdxFreeCameraPrimDataSource, UsdImagingDataSourceCameraPrim, UsdImagingDataSourceTetMesh, HdDataSourceLegacyPrim, UsdImagingDataSourceBasisCurves, UsdImagingDataSourceVolumePrim, UsdImagingDataSourceMeshTopology, UsdSkelImagingDataSourceResolvedSkeletonPrim, UsdImagingDataSourceVisibility, HdDataSourceLegacyTaskPrim, UsdImagingDataSourceMaterial, UsdImagingRerootingContainerDataSource, UsdSkelImagingDataSourceBindingAPI, UsdImagingDataSourceGprim, UsdImagingDataSourceStage, UsdImagingDataSourceFieldAsset, HdMapContainerDataSource, UsdImagingDataSourceRenderPassPrim, UsdSkelImagingDataSourceAnimationPrim, UsdImagingDataSourceCamera, UsdImagingDataSourceTetMeshTopology, UsdImagingDataSourceBasisCurvesTopology, UsdImagingDataSourcePrimvars, UsdSkelImagingDataSourceBlendShapePrim, HdLazyContainerDataSource, UsdImagingDataSourceSubdivisionTags, UsdImagingDataSourceVolumeFieldBindings, UsdImagingDataSourcePointsPrim, UsdImagingDataSourceUsdPrimInfo, UsdImagingDataSourceNurbsCurvesPrim, UsdImagingDataSourceNurbsPatchPrim, UsdSkelImagingDataSourceSkeletonPrim, and UsdImagingDataSourceParticleFieldPrim.

static HD_API HdDataSourceBaseHandle HdContainerDataSource::Get ( const Handle &  container, const HdDataSourceLocator &  locator  )

static

A convenience function: given container, return the descendant identified by locator, which may be at any depth. Returns container itself on an empty locator, or null if locator doesn't identify a valid descendant.

virtual TfTokenVector HdContainerDataSource::GetNames ( )

pure virtual

Returns the list of names for which Get(...) is expected to return a non-null value. This call is expected to be threadsafe.

Implemented in UsdImagingDataSourcePrim, UsdImagingDataSourceDataSharing, UsdImagingDataSourcePrimOrigin, UsdImagingDataSourceXform, HdsiLocatorCachingSceneIndex::_DataSource, UsdImagingDataSourceExtentsHint, UsdImagingDataSourceExtent, UsdImagingDataSourceMapped, UsdImagingDataSourceRenderVarPrim, UsdImagingDataSourcePrimvar, UsdImagingDataSourceMeshPrim, UsdImagingDataSourcePointInstancerPrim, UsdImagingDataSourceRenderProductPrim, UsdImagingDataSourceTetMeshPrim, UsdImagingDataSourceBasisCurvesPrim, UsdImagingDataSourceMesh, UsdImagingDataSourcePurpose, UsdImagingDataSourceMaterialPrim, UsdImagingDataSourcePointInstancerTopology, UsdSkelImagingDataSourceResolvedPointsBasedPrim, HdxFreeCameraPrimDataSource, UsdImagingDataSourceRenderSettingsPrim, UsdImagingDataSourceFieldAssetPrim, HdOverlayContainerDataSource, UsdImagingDataSourceCustomPrimvars, UsdImagingDataSourceCameraPrim, UsdImagingDataSourceTetMesh, HdDataSourceLegacyPrim, UsdImagingDataSourceBasisCurves, UsdImagingDataSourceVolumePrim, UsdImagingDataSourceMeshTopology, UsdSkelImagingDataSourceResolvedSkeletonPrim, UsdImagingDataSourceVisibility, HdDataSourceLegacyTaskPrim, UsdImagingDataSourceMaterial, UsdImagingRerootingContainerDataSource, UsdImagingDataSourceFieldAsset, UsdSkelImagingDataSourceBindingAPI, HdMapContainerDataSource, UsdImagingDataSourceCamera, UsdImagingDataSourceGprim, UsdImagingDataSourceStage, UsdImagingDataSourceTetMeshTopology, UsdImagingDataSourceBasisCurvesTopology, UsdImagingDataSourcePrimvars, UsdImagingDataSourceRenderPassPrim, UsdSkelImagingDataSourceAnimationPrim, UsdImagingDataSourceSubdivisionTags, UsdImagingDataSourceVolumeFieldBindings, HdLazyContainerDataSource, UsdSkelImagingDataSourceBlendShapePrim, UsdImagingDataSourceUsdPrimInfo, UsdImagingDataSourceNurbsCurvesPrim, UsdImagingDataSourceNurbsPatchPrim, and UsdSkelImagingDataSourceSkeletonPrim.
