Detailed Description

An implementation of the OpenSWATH Spectrum Access interface completely in memory.

This implementation of the spectrum access interface ensures that all data is held completely in memory and is quickly accessible. This class can be generated by passing any object implementing the Spectrum Access interface and guarantees to provide the same access to the raw data as the original object with the added benefits (and downside) of keeping all data in system memory.

A possible example

fillData(data_access); // assume that data_access points to some data
OpenSwath::ISpectrumAccess * in_memory_data_access = SpectrumAccessOpenMSInMemory(data_access);
SpectrumAccessOpenMSInMemory(OpenSwath::ISpectrumAccess &origin)
Constructor.
The interface of a mass spectrometry experiment.
Definition: openswathalgo/include/OpenMS/OPENSWATHALGO/DATAACCESS/ISpectrumAccess.h:51

After executing this code, two variables exist: data_access which provides access to the original data but does so in one of multiple ways which is not transparent to the user. However, in_memory_data_access will provide access to the same data but with the guarantee that the data is available in memory and not read from the disk.
