| Subject: | [Caml-list] polymorphic methods in objects? |
Hi,
Why can't objects have polymorphic methods ? I'm trying a compile and
ocamlc gets upset because I have a method with an unbound type in its
signature (see below for ocamlc error output).
Must methods be type paramaterized through some kind of a template
mechanism? This seems a bit limiting: the methods of an object would have
their type signature fixed across the lifetime of an object.
method dummy_init : 'a -> unit
method dump : out_channel -> unit
method init : unit -> unit
method join : string -> unit
method null : unit -> unit
method resolv : string -> hmap option
end
The method dummy_init has type 'a -> unit where 'a is unbound
make: *** [pastry.cmo] Error 2
Thanks,
Lex
