Detailed Description

template<class ValueT, class ReferenceT, class PointerT, class SpectrumIteratorT, class PeakIteratorT>
class OpenMS::Internal::AreaIterator< ValueT, ReferenceT, PointerT, SpectrumIteratorT, PeakIteratorT >

Forward iterator for an area of peaks in an experiment.

This iterator allows us to move through the data structure in a linear manner i.e. we don't need to jump to the next spectrum manually.

Ion mobility can also be filtered for: the low/high range for IM are used to skip over spectra in the given RT range whose drift time is not within the given range. I.e. the RT range could contain multiple IM frames.

Note
This iterator iterates over spectra with same MS level as the MS level of the begin() spectrum in Param! You can explicitly set another MS level as well.
