Graph of Term identifiers.

This is a graph where all information is distilled to term identifiers and relations between them, that are also labeled with term identifiers.

type node = tid
val start : node

start is a pseudo node that is used as the entry node of a graph.

val exit : node

exit is a pseudo node that is used as the exit node of a graph.

include Graphlib.Std.Graph with type node := tid and type Node.label = tid and type Edge.label = tid
type t

type of graph

type edge

type of edges

module Node : Graphlib.Std.Node with type graph = t and type t = tid and type edge = edge with type label = tid

Graph nodes.

module Edge : Graphlib.Std.Edge with type graph = t and type t = edge and type node = tid with type label = tid

Graph edges

val empty : t

empty is an empty graph

val nodes : t -> tid Regular.Std.seq

nodes g returns all nodes of graph g in an unspecified order

val edges : t -> edge Regular.Std.seq

edges g returns all edges of graph g in an unspecified order

val is_directed : bool

is_directed is true if graph is a directed graph.

val number_of_edges : t -> int

number_of_edges g returns the size of a graph g.

val number_of_nodes : t -> int

number_of_nodes g returns the order of a graph g

All graphs provides a common interface for any opaque data structure

include Regular.Std.Opaque.S with type t := t
include Core_kernel.Comparable.S with type t := t
include Base.Comparable.S with type t := t
include Base.Comparisons.S with type t := t

val (>=) : t -> t -> bool
val (<=) : t -> t -> bool
val (=) : t -> t -> bool
val (>) : t -> t -> bool
val (<) : t -> t -> bool
val (<>) : t -> t -> bool
val equal : t -> t -> bool
val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~compare:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool

between t ~low ~high means low <= t <= high

val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).

val clamp : t -> min:t -> max:t -> t Base.Or_error.t

type comparator_witness
val validate_lbound : min:t Base.Maybe_bound.t -> t Base.Validate.check
val validate_ubound : max:t Base.Maybe_bound.t -> t Base.Validate.check

include Core_kernel.Hashable.Common with type t := t
val compare : t -> t -> Base.Int.t

val hashable : t Base.Hashable.t
module Table : Core_kernel.Hashtbl.S with type key = t
module Hash_set : Core_kernel.Hash_set.S with type elt = t

All graphs are printable.

include Regular.Std.Printable.S with type t := t
val to_string : t -> string

to_string x returns a human-readable representation of x

val str : unit -> t -> string

str () t is formatted output function that matches "%a" conversion format specifier in functions, that prints to string, e.g., sprintf, failwithf, errorf and, surprisingly all Lwt printing function, including Lwt_io.printf and logging (or any other function with type ('a,unit,string,...) formatN`. Example:

Or_error.errorf "type %a is not valid for %a"
  Type.str ty Exp.str exp
val pps : unit -> t -> string

synonym for str

val ppo : Core_kernel.Out_channel.t -> t -> unit

will print to a standard output_channel, useful for using in printf, fprintf, etc.

val pp_seq : Format.formatter -> t Core_kernel.Sequence.t -> unit

prints a sequence of values of type t

this will include pp function from Core that has type t printer, and can be used in Format.printf family of functions

include Core_kernel.Pretty_printer.S with type t := t
val pp : Base.Formatter.t -> t -> unit
