type 'a t = 'a ref
val map : ('a -> 'b) -> 'a t -> 'b t

Transform the value.

val create : 'a -> 'a t

Alias to ref.

val iter : ('a -> unit) -> 'a t -> unit

Call the function on the content of the reference.

val get_then_incr : int t -> int

get_then_incr r increments r and returns its old value, think r++.

  • since 0.17
val swap : 'a t -> 'a t -> unit

swap t1 t2 puts !t2 in t1 and !t1 in t2.

  • since 1.4
val compare : 'a ord -> 'a t ord
val equal : 'a eq -> 'a t eq
val to_list : 'a t -> 'a list
val to_iter : 'a t -> 'a iter
  • since 3.0
