Detailed Description

template<class ParticleCell, class ParticleFunctor, bool bidirectional = true>
class autopas::internal::CellFunctor< ParticleCell, ParticleFunctor, bidirectional >

A cell functor.

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

Template Parameters

ParticleCell
ParticleFunctor	the functor which
bidirectional	if no newton3 is used processCellPair(cell1, cell2) should also handle processCellPair(cell2, cell1)

Constructor & Destructor Documentation

CellFunctor()

template<class ParticleCell , class ParticleFunctor , bool bidirectional = true>

autopas::internal::CellFunctor< ParticleCell, ParticleFunctor, bidirectional >::CellFunctor ( ParticleFunctor *  f, const double  sortingCutoff, DataLayoutOption  dataLayout, bool  useNewton3  )

inlineexplicit

The constructor of CellFunctor.

Parameters

f	The ParticleFunctor 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.

processCell()

template<class ParticleCell , class ParticleFunctor , bool bidirectional>

void autopas::internal::CellFunctor< ParticleCell, ParticleFunctor, bidirectional >::processCell

(

ParticleCell &

cell

)

Process the interactions inside one cell.

Parameters

cell	All pairwise interactions of particles inside this cell are calculated.

processCellPair()

template<class ParticleCell , class ParticleFunctor , bool bidirectional>

void autopas::internal::CellFunctor< ParticleCell, ParticleFunctor, bidirectional >::processCellPair	(	ParticleCell &	cell1,

	)

Process the interactions between the particles of cell1 with particles of cell2.

Parameters

cell1
cell2
sortingDirection	Normalized vector connecting centers of cell1 and cell2. If no parameter or {0, 0, 0} is given, sorting will be disabled.

setSortingThreshold()

(

size_t

sortingThreshold

)

Set the sorting-threshold If the sum of the number of particles in two cells is greater or equal to that value, the CellFunctor creates a sorted view of the particles to avoid unnecessary distance checks.

Parameters

sortingThreshold
