Symmetric iterator for the neighborhood of the cell structures. More...

Detailed Description

template<unsigned int dim, typename Cell, typename vector_pos_type, unsigned int impl>
class CellNNIteratorSym< dim, Cell, vector_pos_type, RUNTIME, impl >

Symmetric 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: if we query the neighborhood of p and q is the neighborhood of p when we will query the neighborhood of q p is not present. This is useful to implement formula like \( \sum_{q = neighborhood(p) and p <= q} \)

Template Parameters

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