Operators

Datatype constructor

Bounds a semi-lattice

val is_bottom : 'a t -> bool

Access

val non_bottom : 'a t -> 'a
val value : bottom:'a -> 'a t -> 'a
val hash : ('a -> int) -> 'a t -> int

Datatype

val equal : ('a -> 'a -> bool) -> 'a t -> 'a t -> bool
val compare : ('a -> 'a -> int) -> 'a t -> 'a t -> int
val pretty_bottom : Stdlib.Format.formatter -> unit

Pretty-printing

val pretty : (Stdlib.Format.formatter -> 'a -> unit) -> Stdlib.Format.formatter -> 'a t -> unit
val is_included : ('a -> 'b -> bool) -> 'a t -> 'b t -> bool
val join : ('a -> 'a -> 'a) -> 'a t -> 'a t -> 'a t
val join_list : ('a -> 'a -> 'a) -> 'a t list -> 'a t
val narrow : ('a -> 'a -> 'a t) -> 'a t -> 'a t -> 'a t
val iter : ('a -> unit) -> 'a t -> unit
val bind : ('a -> 'b t) -> 'a t -> 'b t
val fold : bottom:'b -> ('a -> 'b) -> 'a t -> 'b
val map : ('a -> 'b) -> 'a t -> 'b t
val zip : 'a t -> 'b t -> ('a * 'b) t

In a lattice where the elements are lists of non-bottom values, the empty list is the bottom case.

val to_option : 'a t -> 'a option

Conversion

val of_option : 'a option -> 'a t
val to_list : 'a t -> 'a list
val bot_of_list : 'a list -> 'a list t
val list_of_bot : 'a list t -> 'a list
val list_values : 'a t list -> 'a list
val add_to_list : 'a t -> 'a list -> 'a list

elt >:: list adds elt to the list if it is not bottom.
