Hi Stuart,
When I try using deftype I get the following error:
java.lang.IllegalArgumentException: No method in multimethod 'print-
dup' for dispatch value: class user.Y__5
Do I have to supply my own print-dup for the new type for this to
work?
Here is the code:
(import
'(java.io StringReader PushbackReader))
(deftype Y [a b])
(defn serialize [x]
(binding [*print-dup* true] (pr-str x)))
(defn deserialize [x]
(let [r (new PushbackReader (new StringReader x))]
(read r)))
(def y (Y "a" "b"))
(deserialize (serialize y))
I'm thinking the easiest way to accomplish what I need is to serialize
the structmaps as hashmaps when writing them, and then deserialize the
hashmap into a new structmap when reading them.
