class RGL::DFSVisitor
A DFSVisitor
is needed by the {Graph#depth_first_search} and {Graph#depth_first_visit} methods of a graph. Besides the eventpoints of {GraphVisitor}, it provides an additional eventpoint start_vertex
, which is called when a depth_first_search
starts a new subtree of the depth first forest that is defined by the search.
