	Hashing function used in the hashtable to distribute the keys.
Intersection Functions
Function computing interation between entity-entity, entity-node and node-node. Returns true if there is an interaction. A possible implementation is to use a templated function.

Detailed Description

Example specialization which is not really implemented.

Member Typedef Documentation

key_t

using key_t

Specify the space filling curves to use in the domain and the N-Tree construction.

The provided class must derive from the CRTP filling_curve_key.

index_spaces

using index_spaces

Mandatory index spaces featured by the N-Tree interface.

This allows the access to the two index spaces entities and nodes.

Member Data Documentation

dimension

unsigned int dimension

staticconstexpr

Dimension of the N-Tree.

It can be 1, 2 or 3 for a binary tree, quadtree or octree respectively.

max_neighbors

unsigned int max_neighbors

staticconstexpr

Maximum number of neighbors per entities.

This is used to compute neighbors list on GPU architectures.
