const RemoteIndices & remoteIndices() const
Get the underlying remote indices.
Definition: owneroverlapcopy.hh:471
Provides a map between global and local indices.
const_iterator end() const
Get an iterator over all remote index lists.

static const Vertex UNAGGREGATED
Identifier of not yet aggregated vertices.
Definition: aggregates.hh:566
constexpr auto get(std::integer_sequence< T, II... >, std::integral_constant< std::size_t, pos >={})
Return the entry at position pos of the given sequence.
Definition: integersequence.hh:22
V::value_type IndexedType
The type we get at each index with operator[].
