type 'a uref

Union-find with union by rank and path compression

This is an implementation of Tarjan's union-find data structure using generics. The interface is analagous to standard references, with the addition of a union operation which makes two references indistinguishable.

val uref : 'a -> 'a uref

Create a new uref

val equal : ('a uref * 'a uref) -> bool

Test whether two urefs share the same equivalence class

val deref : 'a uref -> 'a

Extract the contents of this reference

val update : ('a uref * 'a) -> unit

Update the value stored in this reference

val unify : (('a * 'a) -> 'a) -> ('a uref * 'a uref) -> unit

unify f (p,q) unifies references p and q, making them indistinguishable. The contents of the reference are the result of f

val union : ('a uref * 'a uref) -> unit

unify (p,q) unifies references p and q, making them indistinguishable. The contents of the reference are the contents of one of the first or second arguments (unspecified)
