Detailed Description

Base class for all prim adapters which only want to indicate that an ancestor prim is responsible for them.

Because Hydra 1.0 prim adapter methods are still present, their pure virtuals must be implemented here (even if they will won't be called).

Member Function Documentation

void UsdImagingRepresentedByAncestorPrimAdapter::_RemovePrim ( SdfPath const &  cachePath,
UsdImagingIndexProxy *  index 
)
inlineoverrideprotectedvirtual

Provides to paramName->UsdAttribute value mappings.

Implements UsdImagingPrimAdapter.

Definition at line 97 of file representedByAncestorPrimAdapter.h.

PopulationMode UsdImagingRepresentedByAncestorPrimAdapter::GetPopulationMode ( )
overridevirtual

Returns the prim's behavior with regard to population and invalidation. See PopulationMode for possible values.

Reimplemented from UsdImagingPrimAdapter.

void UsdImagingRepresentedByAncestorPrimAdapter::MarkDirty ( UsdPrim const &  prim,
SdfPath const &  cachePath,
HdDirtyBits  dirty,
UsdImagingIndexProxy *  index 
)
inlineoverridevirtual

Returns a bit mask of attributes to be updated, or HdChangeTracker::AllDirty if the entire prim must be resynchronized.

changedFields contains a list of changed scene description fields for this prim. This may be empty in certain cases, like the addition of an inert prim spec for the given prim.

The default implementation returns HdChangeTracker::AllDirty if any of the changed fields are plugin metadata fields, HdChangeTracker::Clean otherwise.

Implements UsdImagingPrimAdapter.

Definition at line 89 of file representedByAncestorPrimAdapter.h.

SdfPath UsdImagingRepresentedByAncestorPrimAdapter::Populate ( UsdPrim const &  prim,
UsdImagingIndexProxy *  index,
UsdImagingInstancerContext const *  instancerContext = nullptr 
)
overridevirtual

Called to populate the RenderIndex for this UsdPrim. The adapter is expected to create one or more prims in the render index using the given proxy.

Implements UsdImagingPrimAdapter.

HdDirtyBits UsdImagingRepresentedByAncestorPrimAdapter::ProcessPropertyChange ( UsdPrim const &  prim,
SdfPath const &  cachePath,
TfToken const &  propertyName 
)
overridevirtual

Returns a bit mask of attributes to be updated, or HdChangeTracker::AllDirty if the entire prim must be resynchronized.

Implements UsdImagingPrimAdapter.

void UsdImagingRepresentedByAncestorPrimAdapter::TrackVariability ( UsdPrim const &  prim,
SdfPath const &  cachePath,
HdDirtyBits *  timeVaryingBits,
UsdImagingInstancerContext const *  instancerContext = nullptr 
) const
inlineoverridevirtual

For the given prim, variability is detected and stored in timeVaryingBits. Initial values are cached into the value cache.

This method is expected to be called from multiple threads.

Implements UsdImagingPrimAdapter.

Definition at line 67 of file representedByAncestorPrimAdapter.h.

void UsdImagingRepresentedByAncestorPrimAdapter::UpdateForTime ( UsdPrim const &  prim,
SdfPath const &  cachePath,
UsdTimeCode  time,
HdDirtyBits  requestedBits,
UsdImagingInstancerContext const *  instancerContext = nullptr 
) const
inlineoverridevirtual

Populates the cache for the given prim, time and requestedBits.

This method is expected to be called from multiple threads.

Implements UsdImagingPrimAdapter.
