Module `BatHashcons.MakeTable`

Parameters

module HT : BatHashtbl.HashedType

Signature

type key = HT.t

type of objects in the table

type t

type of the table

val create : int -> t

create n creates a table with at least n cells.

val clear : t -> unit

clear tab removes all entries from the table tab.

val hashcons : t -> key -> key hobj

hashcons tab k returns either k, adding it to the table tab as a side effect, or if k is already in the table then it returns the hashed object corresponding to that entry.

raises Failure
if number of objects with the same hash reaches system limit of array size

val iter : (key hobj -> unit) -> t -> unit

iter f tab applies f to every live hashed object in the table tab.

val fold : (key hobj -> 'a -> 'a) -> t -> 'a -> 'a

fold f tab x0 folds f across every live hashed object in the table tab, starting with value x0

val count : t -> int

count tab returns a count of how many live objects are in tab. This can decrease whenever the GC runs, even during execution, so consider the returned value as an upper-bound.
