Hi,
Can someone teach me how I can override the "toString" method for a struct ?
Here's a code snippet that shows what I'm trying to do:
user> (defstruct bookinfo :book :filename)
user> (struct bookinfo "hello" "world") => {:book "hello", :filename "world"}
I would like to override the "toString" method on a struct so that the
following behavior is true:
user> (struct bookinfo "hello" "world") => "hello"
In Common Lisp, I would simply define a method on (print-object). What
would be the equivalent thing in Clojure?
I already tried the following but it doesn't seem to work
(sorry...i've been programming Clojure for only two days):
user> (defmulti .toString class)
user> (defmethod .toString clojure.lang.PersistentStructMap [s]
(:book s))
Thanks for your help.
Regards,
Jung Ko
