Gmap.Vertex
Provide a mapping function from a mapping of vertices.
val map : (G_Src.V.t -> G_Dst.vertex) -> G_Src.t -> G_Dst.t
map f g
applies f
to each vertex of g
and so builds a new graph based on g
val filter_map : (G_Src.V.t -> G_Dst.vertex option) -> G_Src.t -> G_Dst.t
filter_map f g
applies f
to each vertex of g
and so builds a new graph based on g
; if None
is returned by f
the vertex is omitted in the new graph.
