include Lattice_type.AI_Lattice_with_cardinal_one with type t := t and type widen_hint = O.t
include Lattice_type.Bounded_Join_Semi_Lattice with type t := t
include Lattice_type.Join_Semi_Lattice with type t := t

datatype of element of the lattice

include Datatype.S with type t := t
include Datatype.S_no_copy with type t := t
include Datatype.Ty with type t := t
val ty : t Type.t
val name : string

Unique name of the datatype.

val descr : t Descr.t

Datatype descriptor.

val packed_descr : Structural_descr.pack

Packed version of the descriptor.

val reprs : t list

List of representants of the descriptor.

val equal : t -> t -> bool

Equality: same spec than Stdlib.(=).

val compare : t -> t -> int

Comparison: same spec than Stdlib.compare.

val hash : t -> int

Hash function: same spec than Hashtbl.hash.

val pretty : Format.formatter -> t -> unit

Pretty print each value in an user-friendly way.

val mem_project : (Project_skeleton.t -> bool) -> t -> bool

mem_project f x must return true iff there is a value p of type Project.t in x such that f p returns true.

val copy : t -> t

Deep copy: no possible sharing between x and copy x.

val join : t -> t -> t

over-approximation of union

val is_included : t -> t -> bool

is first argument included in the second?

val bottom : t

smallest element

include Lattice_type.With_Top with type t := t
val top : t

largest element

include Lattice_type.With_Widening with type t := t with type widen_hint = O.t
type widen_hint = O.t

hints for the widening

val widen : widen_hint -> t -> t -> t

widen h t1 t2 is an over-approximation of join t1 t2. Assumes is_included t1 t2

include Lattice_type.With_Cardinal_One with type t := t
val cardinal_zero_or_one : t -> bool
include Lattice_type.With_Narrow with type t := t
val narrow : t -> t -> t

over-approximation of intersection

include Lattice_type.With_Under_Approximation with type t := t

under-approximation of union

val meet : t -> t -> t

under-approximation of intersection

include Lattice_type.With_Intersects with type t := t
val intersects : t -> t -> bool

intersects t1 t2 returns true iff the intersection of t1 and t2 is non-empty.
