Vertex-initializer functor for breadth_first_search().
Initializes vertices' BFS-parent, BFS-level. If the vertex is the source, the level is one (active). All other vertices' levels are set to zero (inactive). All vertices' BFS-parents are set to their own descriptors.
VD | Type of the vertex-descriptor. |
LevelType | Type of the vertex-level. |
