Module InferModules__Propset

Functions for Sets of Propositions with and without sharing

Sets of Propositions

type t

Sets of propositions. The invariant is maintaned that Prop.prop_rename_primed_footprint_vars is called on any prop added to the set.

val compare : t -> t -> int

Compare propsets

val singleton : InferIR.Tenv.t -> InferModules.Prop.normal InferModules.Prop.t -> t

Singleton set.

val mem : InferModules.Prop.normal InferModules.Prop.t -> t -> bool

Set membership.

val union : t -> t -> t

Set union.

val inter : t -> t -> t

Set intersection

val add : InferIR.Tenv.t -> InferModules.Prop.normal InferModules.Prop.t -> t -> t

Add prop to propset.

val diff : t -> t -> t

Set difference.

val empty : t

The empty set of propositions.

val size : t -> int

Size of the set

val from_proplist : InferIR.Tenv.t -> InferModules.Prop.normal InferModules.Prop.t list -> t
val to_proplist : t -> InferModules.Prop.normal InferModules.Prop.t list
val map : InferIR.Tenv.t -> (InferModules.Prop.normal InferModules.Prop.t -> InferModules.Prop.normal InferModules.Prop.t) -> t -> t

Apply function to all the elements of the propset.

val map_option : InferIR.Tenv.t -> (InferModules.Prop.normal InferModules.Prop.t -> InferModules.Prop.normal InferModules.Prop.t option) -> t -> t

Apply function to all the elements of the propset, removing those where it returns None.

val fold : ('a -> InferModules.Prop.normal InferModules.Prop.t -> 'a) -> 'a -> t -> 'a

fold f pset a computes (f pN ... (f p2 (f p1 a))...), where p1 ... pN are the elements of pset, in increasing order.

val iter : (InferModules.Prop.normal InferModules.Prop.t -> unit) -> t -> unit

iter f pset computes (f p1;f p2;..;f pN) where p1 ... pN are the elements of pset, in increasing order.

val partition : (InferModules.Prop.normal InferModules.Prop.t -> bool) -> t -> t * t
val subseteq : t -> t -> bool
val is_empty : t -> bool

Set emptiness check.

val filter : (InferModules.Prop.normal InferModules.Prop.t -> bool) -> t -> t

Pretty print

val d : InferModules.Prop.normal InferModules.Prop.t -> t -> unit

dump a propset coming form the given initial prop
