USDIMAGING_API VtValue | GetValue (HdSampledDataSource::Time shutterOffset) override |
Returns the extracted path array value of the attribute, as a VtValue. | |
USDIMAGING_API VtArray< SdfPath > | GetTypedValue (HdSampledDataSource::Time shutterOffset) override |
Returns the extracted path array value of the attribute. | |
USDIMAGING_API bool | GetContributingSampleTimesForInterval (HdSampledDataSource::Time startTime, HdSampledDataSource::Time endTime, std::vector< HdSampledDataSource::Time > *outSampleTimes) override |
Returns false indicating USD relationhips cannot vary with time. | |

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. | |
