	HD_DECLARE_DATASOURCE (UsdImagingDataSourceAttributeColorSpace)

VtValue	GetValue (HdSampledDataSource::Time shutterOffset) override
	Returns the VtValue of the colorspace for the attribute.

TfToken	GetTypedValue (HdSampledDataSource::Time shutterOffset) override
	Returns the extracted TfToken value of the color space metadata on the attribute.

bool	GetContributingSampleTimesForInterval (HdSampledDataSource::Time startTime, HdSampledDataSource::Time endTime, std::vector< HdSampledDataSource::Time > *outSampleTimes) override
	Returns false since we do not expect the color space value to vary over time.

	HD_DECLARE_DATASOURCE_ABSTRACT (HdTypedSampledDataSource< T >)

virtual T	GetTypedValue (Time shutterOffset)=0
	Returns the value of this data source at frame-relative time `shutterOffset`, as type `T`.

Public Member Functions inherited from HdSampledDataSource
	HD_DECLARE_DATASOURCE_ABSTRACT (HdSampledDataSource)

virtual VtValue	GetValue (Time shutterOffset)=0
	Returns the value of this data source at frame-relative time `shutterOffset`.

virtual bool	GetContributingSampleTimesForInterval (Time startTime, Time endTime, std::vector< Time > *outSampleTimes)=0
	Given a shutter window of interest (`startTime` and `endTime` relative to the current frame), return a list of sample times for the caller to query with GetValue such that the caller can reconstruct the signal over the shutter window.
