CellNNIteratorM< dim, Cell, sh_byte, RUNTIME, impl > Class Template Reference

Iterator for the neighborhood of the cell structures. More...

Detailed Description

template<unsigned int dim, typename Cell, unsigned int sh_byte, unsigned int impl>
class CellNNIteratorM< dim, Cell, sh_byte, RUNTIME, impl >

Iterator for the neighborhood of the cell structures.

In general you never create it directly but you get it from the CellList structures

It iterate across all the element of the selected cell and the near cells

Note

to calculate quantities that involve a total reduction (like energies) use the CellIteratorSymRed

Template Parameters

dim	dimensionality of the space where the cell live
Cell	cell type on which the iterator is working
impl	implementation specific options NO_CHECK do not do check on access, SAFE do check on access
