Parameters

module L : OrderedType
module R : OrderedType

Signature

type t
type left = L.t
type right = R.t
val empty : t
val is_empty : t -> bool
val equal : t -> t -> bool
val compare : t -> t -> int
val add : left -> right -> t -> t

Add left and right correspondence to bijection such that left and right are unique in their respective sets and only correspond to each other.

val cardinal : t -> int

Number of bindings. O(n) time.

val mem : left -> right -> t -> bool

Check both sides for key membership.

val mem_left : left -> t -> bool

Check for membership of correspondence using left key.

val mem_right : right -> t -> bool

Check for membership of correspondence using right key.

val find_left : left -> t -> right
val find_right : right -> t -> left
val remove : left -> right -> t -> t

Remove the left, right binding if it exists. Return the same bijection otherwise.

val remove_left : left -> t -> t

Remove the binding with left key if it exists. Return the same bijection otherwise.

val remove_right : right -> t -> t

Remove the binding with right key if it exists. Return the same bijection otherwise.

val list_left : t -> (left * right) list

Return the bindings as a list of (left, right) values.

val list_right : t -> (right * left) list

Return the bindings as a list of (right, left) values.

val add_seq : (left * right) sequence -> t -> t
val of_seq : (left * right) sequence -> t
val to_seq : t -> (left * right) sequence
val add_list : (left * right) list -> t -> t
val of_list : (left * right) list -> t
val to_list : t -> (left * right) list
