triqs::mesh::MeshPoint

#include <triqs/mesh/concepts.hpp>

Detailed Description

Concept for a mesh point.

Every mesh point mp of type MP

• belongs to a mesh MP::mesh_t,
• has a unique index mp.index() that identifies a mesh point within the mesh,
• has a data index mp.data_index() that is used to access function values/coefficients stored in GF containers and
• has a hash value mp.mesh_hash() that is used to check if a mesh point belongs to or is compatible with a mesh.

Template Parameters

MP	Mesh point type.
