SiPixelRecHitQuality::QualWordType PixelCPEBase::rawQualityWord ( ClusterParam & theClusterParam ) const

private

A convenience method to fill a whole SiPixelRecHitQuality word in one shot. This way, we can keep the details of what is filled within the pixel code and not expose the Transient SiPixelRecHit to it as well. The name of this function is chosen to match the one in SiPixelRecHit.
