Constructor Detail

MSnSpectrum

public MSnSpectrum()

Constructor for the spectrum.

MSnSpectrum

public MSnSpectrum(int level,

           java.lang.String spectrumTitle,
           java.lang.String fileName)

Minimal constructor for the spectrum. The peak list is not loaded in order to reduce memory consumption.

Parameters:

level - MS level

precursor - precursor

spectrumTitle - spectrum title

fileName - file name

MSnSpectrum

public MSnSpectrum(int level,
           Precursor precursor,
           java.lang.String spectrumTitle,
           java.util.HashMap<java.lang.Double,Peak> peakMap,
           java.lang.String fileName)

Constructor for the spectrum.

Parameters:

level - MS level

precursor - precursor

spectrumTitle - spectrum title

peakMap - set of peaks

fileName - file name

MSnSpectrum

public MSnSpectrum(int level,
           Precursor precursor,
