Detailed Description

template<class ParticleCell_T, class ParticleFunctor_T, bool bidirectional = true>
class autopas::internal::CellFunctor3B< ParticleCell_T, ParticleFunctor_T, bidirectional >

A cell functor.

This functor is built from the normal Functor of the template type ParticleFunctor_T. It is an internal object to handle interactions between up to three cells of particles.

Template Parameters

ParticleCell_T
ParticleFunctor_T	the functor which is used for particle interactions
bidirectional	if no newton3 is used, processCellPair(..) and processCellPair(..) should handle interactions for particles from all cells.

autopas::internal::CellFunctor3B< ParticleCell_T, ParticleFunctor_T, bidirectional >::CellFunctor3B ( ParticleFunctor_T &  f, const double  sortingCutoff, DataLayoutOption  dataLayout, bool  useNewton3  )

inlineexplicit

The constructor of CellFunctor3B.

Parameters

f	The particle functor, which should be used for the interaction.
sortingCutoff	This parameter indicates the maximal distance the sorted particles are to interact. This parameter is only relevant for optimization (sorting). This parameter normally should be the cutoff, for building verlet lists, this should be cutoff+skin.
dataLayout	The data layout to be used.
useNewton3	Parameter to specify whether newton3 is used or not.
