Functor Strongly_connected_components.Make

module Make: functor (Id : Identifiable.S) -> S  with module Id := Id

Parameters:

Id : Identifiable.S

module Id: Identifiable.S

type directed_graph = Id.Set.t Id.Map.t

If (a -> set) belongs to the map, it means that there are edges from a to every element of set. It is assumed that no edge points to a vertex not represented in the map.

type component =

`\|`	`Has_loop of Id.t list`
`\|`	`No_loop of Id.t`

val connected_components_sorted_from_roots_to_leaf : directed_graph ->
       component array

val component_graph : directed_graph ->
       (component * int list) array
