Detailed Description

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

The MSDataWritingConsumer is able to write spectra and chromatograms to disk on the fly (as soon as they are consumed). This class is abstract and allows the derived class to define how spectra and chromatograms are processed before being written to disk.

If you are looking for class that simply takes spectra and chromatograms and writes them to disk, please use the PlainMSDataWritingConsumer.

Example usage:

MSDataWritingConsumer * consumer = new MSDataWritingConsumer(outfile); // some implementation
consumer->setExpectedSize(specsize, chromsize);
consumer->setExperimentalSettings(exp_settings);
consumer->addDataProcessing(dp); // optional, will be added to all spectra and chromatograms
[...]
// multiple times ...
consumer->consumeSpectrum(spec);
consumer->consumeChromatogram(chrom);
[...]
delete consumer;
MSDataWritingConsumer(String filename)
Constructor.
Note
The first usage of consumeChromatogram or consumeSpectrum will start writing of the mzML header to disk (and the first element).
Currently it is not possible to add spectra after having already added chromatograms since this could lead to a situation with multiple spectrumList tags appear in an mzML file.
The expected size will not be enforced but it will lead to an inconsistent mzML if the count attribute of spectrumList or chromatogramList is incorrect.

Member Function Documentation

◆ addDataProcessing()

virtual void addDataProcessing ( DataProcessing  d)
virtual

Optionally add a data processing method to each chromatogram and spectrum.

The provided DataProcessing object will be added to each chromatogram and spectrum written to to the mzML file.

Parameters
dThe DataProcessing object to be added

Referenced by TOPPOpenSwathBase::prepareChromOutput().

◆ consumeChromatogram()

void consumeChromatogram ( ChromatogramType c)
overridevirtual

Consume a chromatogram.

The chromatogram will be processed using the processChromatogram_ method of the current implementation and then written to the mzML file.

Parameters
cThe chromatogram to be written to mzML

Implements IMSDataConsumer.

Reimplemented in NoopMSDataWritingConsumer.

◆ consumeSpectrum()

void consumeSpectrum ( SpectrumType s)
overridevirtual

Consume a spectrum.

The spectrum will be processed using the processSpectrum_ method of the current implementation and then written to the mzML file.

Parameters
sThe spectrum to be written to mzML

Implements IMSDataConsumer.

Reimplemented in NoopMSDataWritingConsumer.

◆ doCleanup_()

virtual void doCleanup_ ( )
privatevirtual

Cleanup function called by the destructor.

Will write the last tags to the file and close the file stream.

Reimplemented in NoopMSDataWritingConsumer.

◆ getNrChromatogramsWritten()

virtual Size getNrChromatogramsWritten ( )
virtual

Return the number of chromatograms written.

◆ getNrSpectraWritten()

virtual Size getNrSpectraWritten ( )
virtual

Return the number of spectra written.

◆ processChromatogram_()

virtual void processChromatogram_ ( ChromatogramType c)
privatepure virtual

Process a chromatogram before storing to disk.

Redefine this function to determine chromatogram processing before writing to disk.

Implemented in NoopMSDataWritingConsumer, and PlainMSDataWritingConsumer.

◆ processSpectrum_()

virtual void processSpectrum_ ( SpectrumType s)
privatepure virtual

Process a spectrum before storing to disk.

Redefine this function to determine spectra processing before writing to disk.

Implemented in NoopMSDataWritingConsumer, and PlainMSDataWritingConsumer.

◆ setExpectedSize()

void setExpectedSize ( Size  expectedSpectra,
Size  expectedChromatograms 
)
overridevirtual

Set expected size of spectra and chromatograms to be written.

These numbers will be written in the spectrumList and chromatogramList tag in the mzML file. Therefore, these will contain wrong numbers if the expected size is not set correctly.

Parameters
expectedSpectraNumber of spectra expected
expectedChromatogramsNumber of chromatograms expected

Implements IMSDataConsumer.

Referenced by MzMLSwathFileConsumer::addNewSwathMap_(), and TOPPOpenSwathBase::prepareChromOutput().

◆ setExperimentalSettings()

void setExperimentalSettings ( const ExperimentalSettings exp)
overridevirtual

Set experimental settings for the whole file.

Parameters
expExperimental settings to be used for this file (from this and the first spectrum/chromatogram, the class will deduce most of the header of the mzML file)

Implements IMSDataConsumer.

Reimplemented in NoopMSDataWritingConsumer.

Referenced by TOPPOpenSwathBase::prepareChromOutput().
