Description
-----------
A Distributed Vertex List Graph is a graph whose vertices are
distributed across multiple processes or address spaces. The
``vertices`` and ``num_vertices`` functions retain the same
signatures as in the `Vertex List Graph`_ concept, but return only
the local set (and size of the local set) of vertices.
Notation
--------
G
A type that models the Distributed Vertex List Graph concept.
g
An object of type ``G``.
Refinement of

- `Graph`_
Associated types
----------------
+----------------+---------------------------------------+---------------------------------+
|Vertex |``graph_traits<G>::vertex_descriptor`` |Must model the |
|descriptor type | |`Global Descriptor`_ concept. |
+----------------+---------------------------------------+---------------------------------+
|Vertex iterator |``graph_traits<G>::vertex_iterator`` |Iterates over vertices stored |
|type | |locally. The value type must be |
| | |``vertex_descriptor``. |
+----------------+---------------------------------------+---------------------------------+
|Vertices size |``graph_traits<G>::vertices_size_type``|The unsigned integral type used |
|type | |to store the number of vertices |
| | |in the local subgraph. |

+----------------+---------------------+----------------------+-------------------------------------+
|Number of local |``num_vertices(g)`` |``vertices_size_type``|Returns the number of vertices |
|vertices. | | |stored locally in the graph. |
