Class Documentation

◆ OpenMS::Internal::MzXMLHandler::SpectrumData

struct OpenMS::Internal::MzXMLHandler::SpectrumData

Data necessary to generate a single spectrum.

Small struct holds all data necessary to populate a spectrum at a later timepoint (since reading of the base64 data and generation of spectra can be done at distinct timepoints).
