Detailed Description

File adapter for MzXML 2.1 files.

Constructor & Destructor Documentation

MzXMLFile ( )

Default constructor.

~MzXMLFile ( )

Destructor.

Member Function Documentation

PeakFileOptions& getOptions ( )

Mutable access to the options for loading/storing.

Referenced by FileHandler::loadExperiment(), SwathFile::loadMzXML(), and FileHandler::storeExperiment().

const PeakFileOptions& getOptions ( ) const

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

void load ( const String filename,
MapType map 
)
inline

Loads a map from a MzXML file.

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

Exceptions
Exception::FileNotFoundis thrown if the file could not be opened
Exception::ParseErroris thrown if an error occurs during parsing

References MSExperiment< PeakT, ChromatogramPeakT >::reset(), DocumentIdentifier::setLoadedFilePath(), DocumentIdentifier::setLoadedFileType(), and MzXMLHandler< MapType >::setOptions().

Referenced by FileHandler::loadExperiment(), and SwathFile::loadMzXML().

void setOptions ( const PeakFileOptions )

set options for loading/storing

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

Stores a map in a MzXML file.

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

Exceptions
Exception::UnableToCreateFileis thrown if the file could not be created

Referenced by FileHandler::storeExperiment().

void transform ( const String filename_in,
Interfaces::IMSDataConsumer< MapType > *  consumer,
bool  skip_full_count = false 
)
inline

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_inFilename of input mzML file to transform
consumerConsumer class to operate on the input filename (implementing a transformation)
skip_full_countWhether to skip computing the correct number of spectra and chromatograms in the input file

References MzXMLHandler< MapType >::setMSDataConsumer(), and MzXMLHandler< MapType >::setOptions().

Referenced by SwathFile::loadMzXML().

void transform ( const String filename_in,
Interfaces::IMSDataConsumer< MapType > *  consumer,
MapType map,
bool  skip_full_count = false 
)
inline

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_inFilename of input mzXML file to transform
consumerConsumer class to operate on the input filename (implementing a transformation)
mapMap to store the resulting spectra and chromatograms
skip_full_countWhether to skip computing the correct number of spectra and chromatograms in the input file
