when i run this from the repl:
(def md (MessageDigest/getInstance "SHA-1"))
(. md update (into-array [(byte 1) (byte 2) (byte 3)]))
I get:
No matching method found: update for class java.security.MessageDigest$Delegate
the Java 6 docs for MessageDigest show:
update(byte[] input)
Updates the digest using the specified array of bytes.
and the class of (class (into-array [(byte 1) (byte 2) (byte 3)])) is
[Ljava.lang.Byte;
Am I missing something in the definition of update?
Not creating the class I think I am?
Not passing it the type I think I am?
