Detailed Description

Class that stores the data for one layer.

The data for a layer can be peak data, feature data (feature, consensus), chromatogram or peptide identification data.

For 2D and 3D data, the data is generally accessible through getPeakData() while features are accessible through getFeatureMap() and getConsensusMap(). For 1D data, the current spectrum must be accessed through getCurrentSpectrum().

Peak data is stored using a shared pointer to an MSExperiment data structure as well as a shared pointer to a OnDiscMSExperiment data structure. Note that the actual data may not be in memory as this is not efficient for large files and therefore may have to be retrieved from disk on-demand.

Note
The spectrum for 1D viewing retrieved through getCurrentSpectrum() is a copy of the actual raw data and different from the one retrieved through getPeakData()[index]. Any changes to applied to getCurrentSpectrum() are non-persistent and will be gone the next time the cache is updated. Persistent changes can be applied to getPeakDataMuteable() and will be available on the next cache update.
Layer is mainly used as a member variable of PlotCanvas which holds a vector of LayerDataBase objects.

Member Typedef Documentation

◆ RangeAllType

Constructor & Destructor Documentation

◆ LayerDataBase() [1/4]

LayerDataBase ( )
delete

Default constructor (for virtual inheritance)

◆ LayerDataBase() [2/4]

LayerDataBase ( const DataType  type)
inlineexplicit

C'tor for child classes.

◆ LayerDataBase() [3/4]

LayerDataBase ( const LayerDataBase ld)
default

Copy-C'tor.

◆ LayerDataBase() [4/4]

LayerDataBase ( LayerDataBase &&  ld)
delete

Move-C'tor - do not move from this class since its a virtual base class (diamond problem) and the move c'tor may be called twice (which would loose data!) Instead of painstakingly writing user-defined move c'tors which check for moving for all the direct child classes, we'd rather use copy (which is the automatic fallback, and safe) and incur a small performance hit

◆ ~LayerDataBase()

virtual ~LayerDataBase ( )
virtualdefault

D'tor.
