Dear all,
Clojure 1.2.0
(deftype A [ ^{:unsynchronized-mutable true} foo ]
Object
(hashCode
[x] (set! foo :foo)
5
))
works very nicely.
(deftype A [ ^{:unsynchronized-mutable true} foo ]
Object
(hashCode
[x] (try (set! foo :foo))
))
also works.
(deftype A [ ^{:unsynchronized-mutable true} foo ]
Object
(hashCode
[x] (try (set! foo :foo))
4
))
fails:
Cannot assign to non-mutable: foo
[Thrown class java.lang.IllegalArgumentException]
This is less useless than it seems. (try is called within locking,
which can be useful when setting something unsynchronized)
Is it a known bug? Does it happen to other people than me?
Best regards,
Nicolas.
