◆ MzXMLFile()

MzXMLFile ( )

Default constructor.

◆ ~MzXMLFile()

override

Destructor.

Member Function Documentation

◆ getOptions() [1/2]

PeakFileOptions& getOptions ( )

Mutable access to the options for loading/storing.

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

◆ 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::UnableToCreateFileis thrown if the file could not be created

◆ 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_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

◆ 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_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

◆ 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.
