An class that uses on-disk caching to read and write spectra and chromatograms.
This class provides functions to read and write spectra and chromatograms to disk using a time-efficient format. Reading the data items from disk can be very fast and done in random order (once the in-memory index is built for the file).

Loads a map from a cached MzML file.
filename
The data location (ends in .mzML, expects an adjacent .mzML.cached file) map
A CachedmzML result object

protected |
Stores a map in a cached MzML file.
filename
The data location (ends in .mzML) map
