Detailed Description

Consumer class that writes MS data to disk using the mzML format.

A very simple implementation of MSDataWritingConsumer, not offering the ability to modify the spectra before writing. This is probably the class you want if you want to write mzML files to disk by providing spectra and chromatograms sequentially.
