Detailed Description

This class is used as a context object with global stage information, that gets passed down to datasources to help them answer scene queries.

It's a pure virtual interface to allow for different use cases to override certain behaviors (like getting the time coordinate, or whether we support time-varying tracking).

virtual void UsdImagingDataSourceStageGlobals::FlagAsAssetPathDependent ( const SdfPath &  usdPath ) const

pure virtual

Flags the object at usdPath as dependent on an asset path. usdPath may point to a prim (e.g., if the prim has asset path metadata) or an attribute (e.g., if the attribute has an asset path value).

virtual void UsdImagingDataSourceStageGlobals::FlagAsTimeVarying ( const SdfPath &  hydraPath, const HdDataSourceLocator &  locator  ) const

pure virtual

Flags the given hydraPath as time varying at the given locator.

virtual UsdTimeCode UsdImagingDataSourceStageGlobals::GetTime ( ) const

pure virtual

Returns the current time represented in this instance.
