I can't figure out how to avoid reflection, in the 'update' method of
MessageDigest. It is overloaded on a single argument with either
'byte', 'byte[]', or 'java.nio.ByteBuffer'.
(import '(java.security MessageDigest))
(set! *warn-on-reflection* true)
The compiler didn't seem to like a tag that wasn't actually a class
name:
(def byte-array-class
(class (make-array Byte/TYPE 0)))
;; "Unable to resolve classname: byte-array-class"
(defn update1
[#^MessageDigest md #^{:tag byte-array-class} item]
(.update md item))
And it seems to have no effect if I expand it as the tag:
;; "call to update can't be resolved."
(defn update2
[#^MessageDigest md #^{:tag (class (make-array Byte/TYPE 0))} item]
(.update md item))
In this particular case, I was able to work around the issue one of
two ways, basically by using a different type.
(defn workaround
[#^MessageDigest md item]
(.update md item 0 (count item)))
(defn workaround2
[#^MessageDigest md item]
(.update md (java.nio.ByteBuffer/wrap item)))
Any ideas? BTW, my real use case is in a defmethod, where I handle
several other types for the update.
Thanks,
David
