Detailed Description

Aggregates spectra by retention time.

This consumer will merge spectra passed to it that have the same retention time and will then pass them to the next consumer (see Constructor). Spectra are aggregated using SpectrumAddition::addUpSpectra() which merges the spectra.

Constructor & Destructor Documentation

MSDataAggregatingConsumer()

MSDataAggregatingConsumer ( Interfaces::IMSDataConsumer *  next_consumer )

inline

Constructor.

Note

This does not transfer ownership of the consumer

~MSDataAggregatingConsumer()

~MSDataAggregatingConsumer ( )

override

Constructor.

Flushes data to next consumer

Note

It is essential to not delete the underlying next_consumer before deleting this object, otherwise we risk a memory error

Member Function Documentation

consumeChromatogram()

void consumeChromatogram ( ChromatogramType &  )

overridevirtual

Consume a chromatogram.

The chromatogram will be consumed by the implementation and possibly modified.

Note

The implementation might not allow to consume spectra and chromatograms in any order

Parameters

s	The chromatogram to be consumed

Implements IMSDataConsumer.

consumeSpectrum()

void consumeSpectrum ( SpectrumType &  s )

overridevirtual

Consume a spectrum.

The spectrum will be consumed by the implementation and possibly modified.

Note

The implementation might not allow to consume spectra and chromatograms in any order

Parameters

s	The spectrum to be consumed

Implements IMSDataConsumer.

setExpectedSize()

void setExpectedSize ( Size  expectedSpectra, Size  expectedChromatograms  )

inlineoverridevirtual

Set expected size of spectra and chromatograms to be consumed.

Some implementations might care about the number of spectra and chromatograms to be consumed and need to be informed about this (usually before consuming starts).

Note

Calling this method is optional but good practice.

Parameters

expectedSpectra	Number of spectra expected
expectedChromatograms	Number of chromatograms expected

Implements IMSDataConsumer.

setExperimentalSettings()

void setExperimentalSettings ( const OpenMS::ExperimentalSettings &  exp )

inlineoverridevirtual

Set experimental settings (meta-data) of the data to be consumed.

Some implementations might need to know about the meta-data (or the context) of the spectra and chromatograms to be consumed. This method allows them learn this.

Note

Calling this method is optional but good practice.

Parameters

exp	Experimental settings meta data for the data to be consumed

Implements IMSDataConsumer.
