Subject: [Caml-list] Basic quation about object methods
Hi,

I'm a relatively newbie ocaml user, and I'm currently trying to understand a
basic thing about methods. Can someone clarify the following:

class test =
  object
    val mutable v = 0
    method no_params = v<-v+1; print_int v
    method has_params () = v<-v+1; print_int v
  end;;

Now what's the basic difference between methods "no_params" and
"has_params"? The o'reilly book says "Note that some methods do not need
parameters" and "We usually access instance variables with parameterless
methods.".

Still both of these methods work just the same. 

Thanks for any info.
