Subject: [Caml-list] Recursion between class and value?
Date: Sun, 18 Aug 2002 10:42:00 -0700 [thread overview]
Message-ID: <20020818174932.712167F63@lobus.fungible.com> (raw)
I'd like to be able to have a class and a function be mutually
recursive, kind of like this:
class foo = object
method bar x =
if x > 0 then baz (x - 1)
else ()
end
let baz z =
if z > 0 then
(new foo)#bar (z - 1)
else ()
The best I know how to do is transform baz into a method on foo,
yielding this:
class foo = object (self)
method bar x =
if x > 0 then self#baz (x - 1)
else ()
method baz z =
(* Except for the type recursion, this doesn't have to be a
method on foo. *)
if z > 0 then
(new foo)#bar (z - 1)
else ()
end
let baz z = (new foo)#baz z
The comment points at the ugly part. Is there a better way?
