RawBeamData & RawBeamPosData::GetData (   ) 
 

Access the underlying data. May not necessarily be valid.

bool RawBeamPosData::IsValid (   ) 
 

Return true if the data is valid.

bool RawBeamPosData::SetData (  const RawBeamData &  data  ) 
 

This (re)sets the underlying RawBeamData. A shallow copy is made. The data is sanity checked for being BPM data. If it fails it is invalidated and false is returned.
