Lazy Tree Structure

This structure can be used to represent trees and directed graphs (as infinite trees) in a lazy fashion. Like CCKList, it is a structural type.

type 'a sequence = ('a -> unit) -> unit

type 'a gen = unit -> 'a option

type 'a klist = unit -> [ `Nil | `Cons of 'a * 'a klist ]

type 'a printer = Buffer.t -> 'a -> unit

type 'a formatter = Format.formatter -> 'a -> unit

Basics

type +'a t = unit -> [ `Nil | `Node of 'a * 'a t list ]

val empty : 'a t

val is_empty : _ t -> bool

val singleton : 'a -> 'a t

Tree with only one label

val node : 'a -> 'a t list -> 'a t

Build a node from a label and a list of children

val node1 : 'a -> 'a t -> 'a t

Node with one child

val node2 : 'a -> 'a t -> 'a t -> 'a t

Node with two children

val fold : ('a -> 'b -> 'a) -> 'a -> 'b t -> 'a

Fold on values in no specified order. May not terminate if the tree is infinite.

val iter : ('a -> unit) -> 'a t -> unit

val size : _ t -> int

Number of elements

val height : _ t -> int

Length of the longest path to empty leaves

val map : ('a -> 'b) -> 'a t -> 'b t

val (>|=) : 'a t -> ('a -> 'b) -> 'b t

val cut_depth : int -> 'a t -> 'a t

Cut the tree at the given depth, so it becomes finite.

Graph Traversals

class type 'a pset = object ... end

Abstract Set structure

val set_of_cmp : ?cmp:('a -> 'a -> int) -> unit -> 'a pset

Build a set structure given a total ordering

val dfs : ?pset:'a pset -> 'a t -> [ `Enter of 'a | `Exit of 'a ] klist

Depth-first traversal of the tree

val bfs : ?pset:'a pset -> 'a t -> 'a klist

Breadth first traversal of the tree

val find : ?pset:'a pset -> ('a -> 'b option) -> 'a t -> 'b option

Look for an element that maps to Some _

Pretty printing in the DOT (graphviz) format

module Dot : sig ... end
