Class type

Output signature of the functor Tree.Make.

type node

The type of information attached to the nodes of the tree

type edge

The type of information attached to the edges of the tree

type t =
  1. | Empty
  2. | Node of node * (t * edge) list
val fold : (node -> node -> node) -> node -> t -> node

fold f z t is f (... (f (f z n1) n2) ...) nn, where n1, ..., nn are the nodes of t. The order in which the nodes are presented is unspecified.

val dot_output : string -> string -> ?options:Dot.graph_style list -> t -> unit

dot_output name fname t writes a .dot representation of tree t with name name in file fname. The aspect of the tree can be adjusted with the options optional argument (see Dot.graph_style).

val dot_view : string -> ?options:Dot.graph_style list -> ?dir:string -> ?cmd:string -> t -> int

dot_view name t writes a .dot representation of t in file dir/name.dot and opens it with Graphviz. The output directory dir is specified with the dir optional argument (default: "/tmp"). The command for launching Graphviz is specified with the cmd optional argument (default: "open -a Graphviz"). The options optional argument is the same than defined for dot_output. The function returns the exit code of the corresponding process.
