int domParseIndexedEnd_(const std::string &in, OffsetVector &spectra_offsets, OffsetVector &chromatograms_offsets)
Extract data from a string containing an <indexList> tag.
std::streampos findIndexListOffset(const String &filename, int buffersize=1023)
Tries to extract the indexList offset from an indexedmzML.
int parseOffsets(const String &filename, std::streampos indexoffset, OffsetVector &spectra_offsets, OffsetVector &chromatograms_offsets)
Tries to extract the offsets of all spectra and chromatograms from an indexedmzML.
std::vector< std::pair< std::string, std::streampos > > OffsetVector
The vector containing binary offsets.
