Member Function Documentation

virtual bool IsSupported ( UsdImagingIndexProxy const *  index) const
overridevirtual

Returns true if the adapter can be populated into the target index.

Reimplemented from UsdImagingPrimAdapter.

virtual SdfPath Populate ( UsdPrim const &  prim,
UsdImagingIndexProxy index,
