operator()() [1/2]

std::size_t libMesh::MeshTools::SidesToElemMap::HashFunction::operator() ( const Key &  vertex_ids ) const

inline

The "Hash" template argument.

We just use the same Utility::hashword() function that is used by the various Elem::compute_key() implementations, although here we can assume the sorting has already been done for us. This will be a 32-bit hash when dof_id_type is 32-bits and a 64-bit hash when dof_id_type is 64 bits.

      return cast_int<std::size_t>(Utility::hashword(vertex_ids));
    }

operator()() [2/2]

bool libMesh::MeshTools::SidesToElemMap::HashFunction::operator() ( const Key &  lhs, const Key &  rhs  ) const

inline

The "KeyEqual" template argument.

Calls std::vector::operator==()
