Detailed Description

template<class ParticleCell, class PairwiseFunctor>
class autopas::LCC04SoACellHandler< ParticleCell, PairwiseFunctor >

This class provides the base for traversals using the c08 base step, but rather use 4 instead of 8 colors for domain coloring.

Using 4 instead of 8 colors allows combination of SoA buffers.

The base step processBaseCell() computes one set of pairwise interactions between two cells for each spatial direction based on the baseIndex. After executing the base step on all cells all pairwise interactions for all cells are done.

Template Parameters

ParticleCell	the type of cells.
PairwiseFunctor	The functor that defines the interaction of two particles.
