Destructor.

Member Function Documentation

◆ getOptions() [1/2]

PeakFileOptions& getOptions ( )

Mutable access to the options for loading/storing.

Referenced by extractCachedMetaFilename(), and SwathFile::loadMzXML().

◆ getOptions() [2/2]

const PeakFileOptions& getOptions ( ) const

Non-mutable access to the options for loading/storing.

◆ load()

void load	(	const String &	filename,
		MapType &	map
	)

Loads a map from a MzXML file.

map has to be a MSExperiment or have the same interface.

Exceptions

Exception::FileNotFound	is thrown if the file could not be opened
Exception::ParseError	is thrown if an error occurs during parsing

Referenced by SwathFile::loadMzXML().

◆ setOptions()

void setOptions ( const PeakFileOptions & )

set options for loading/storing

◆ store()

void store	(	const String &	filename,
		const MapType &	map
	)		const

Stores a map in a MzXML file.

map has to be a MSExperiment or have the same interface.

Exceptions

Exception::UnableToCreateFile is thrown if the file could not be created

Referenced by extractCachedMetaFilename().

◆ transform() [1/2]

void transform	(	const String &	filename_in,
		Interfaces::IMSDataConsumer *	consumer,
		bool	skip_full_count = `false`
	)

Transforms a map while loading using the supplied MSDataConsumer.

The result will not be stored directly but is available through the events triggered by the parser and caught by the provided IMSDataConsumer object.

This function should be used if processing and storage of the result can be performed directly in the provided IMSDataConsumer object.

Note: Transformation can be speed up by setting skip_full_count which does not require a full first pass through the file to compute the correct number of spectra and chromatograms in the input file.

Parameters

filename_in	Filename of input mzML file to transform
consumer	Consumer class to operate on the input filename (implementing a transformation)
skip_full_count	Whether to skip computing the correct number of spectra and chromatograms in the input file

Referenced by extractCachedMetaFilename(), and SwathFile::loadMzXML().

◆ transform() [2/2]

void transform	(	const String &	filename_in,
		Interfaces::IMSDataConsumer *	consumer,
		MapType &	map,
		bool	skip_full_count = `false`
	)

Transforms a map while loading using the supplied MSDataConsumer.

The result will be stored in the provided map.

This function should be used if a specific pre-processing should be applied to the data before storing them in a map (e.g. if data-reduction should be applied to the data before loading all data into memory).

Parameters

filename_in	Filename of input mzXML file to transform
consumer	Consumer class to operate on the input filename (implementing a transformation)
map	Map to store the resulting spectra and chromatograms
skip_full_count	Whether to skip computing the correct number of spectra and chromatograms in the input file

◆ transformFirstPass_()

void transformFirstPass_	(	const String &	filename_in,
		Interfaces::IMSDataConsumer *	consumer,
		bool	skip_full_count
	)

protected

Perform first pass through the file and retrieve the meta-data to initialize the consumer.
