Implemented in SpectrumAccessSqMass, SpectrumAccessTransforming, SpectrumAccessOpenMSInMemory, SpectrumAccessOpenMSCached, and SpectrumAccessOpenMS.

lightClone()

virtual boost::shared_ptr<ISpectrumAccess> lightClone ( ) const

pure virtual

Light clone operator to produce a copy for concurrent read access.

This function guarantees to produce a copy of the underlying object that provides thread-safe concurrent read access to the underlying data. It should be implemented with minimal copy-overhead to make this operation as fast as possible.

To use this function, each thread should call this function to produce an individual copy on which it can operate.

Implemented in SpectrumAccessTransforming, SpectrumAccessSqMass, SpectrumAccessQuadMZTransforming, SpectrumAccessOpenMSInMemory, SpectrumAccessOpenMSCached, and SpectrumAccessOpenMS.
