module O : Map.OrderedType

Signature

include Map.S with type 'a t = 'a Map.Make(O).t with type key = O.t
type key = O.t
type 'a t = 'a Map.Make(O).t
val empty : 'a t
val is_empty : 'a t -> bool
val mem : key -> 'a t -> bool
val add : key -> 'a -> 'a t -> 'a t
val singleton : key -> 'a -> 'a t
val remove : key -> 'a t -> 'a t
val merge : (key -> 'a option -> 'b option -> 'c option) -> 'a t -> 'b t -> 'c t
val union : (key -> 'a -> 'a -> 'a option) -> 'a t -> 'a t -> 'a t
val compare : ('a -> 'a -> int) -> 'a t -> 'a t -> int
val equal : ('a -> 'a -> bool) -> 'a t -> 'a t -> bool
val iter : (key -> 'a -> unit) -> 'a t -> unit
val fold : (key -> 'a -> 'b -> 'b) -> 'a t -> 'b -> 'b
val for_all : (key -> 'a -> bool) -> 'a t -> bool
val exists : (key -> 'a -> bool) -> 'a t -> bool
val filter : (key -> 'a -> bool) -> 'a t -> 'a t
val partition : (key -> 'a -> bool) -> 'a t -> 'a t * 'a t
val cardinal : 'a t -> int
val bindings : 'a t -> (key * 'a) list
val min_binding : 'a t -> key * 'a
val max_binding : 'a t -> key * 'a
val choose : 'a t -> key * 'a
val split : key -> 'a t -> 'a t * 'a option * 'a t
val find : key -> 'a t -> 'a
val map : ('a -> 'b) -> 'a t -> 'b t
val mapi : (key -> 'a -> 'b) -> 'a t -> 'b t
val get : key -> 'a t -> 'a option

Safe version of find

val update : key -> ('a option -> 'a option) -> 'a t -> 'a t

update k f m calls f (Some v) if find k m = v, otherwise it calls f None. In any case, if the result is None k is removed from m, and if the result is Some v' then add k v' m is returned.

val of_seq : (key * 'a) sequence -> 'a t

val of_list : (key * 'a) list -> 'a t
val to_list : 'a t -> (key * 'a) list
val pp : ?start:string -> ?stop:string -> ?arrow:string -> ?sep:string -> key printer -> 'a printer -> 'a t printer
val print : ?start:string -> ?stop:string -> ?arrow:string -> ?sep:string -> key formatter -> 'a formatter -> 'a t formatter
