Unquote a java method in clojure

Question

How do I parameterize calls methods in Clojure?

Example:

(def url (java.net.URL. "http://www.google.com"))
(.getHost url) ;; works!
(def host '.getHost)
(host url) ;; Nope :(
(~host url) ;; Nope :(
(eval `(~host url)) ;; Works :s

Answer 1

Right solution:

(def url (URL. "http://www.google.com"))
(def host 'getHost)
(defn dynamic-invoke
  [obj method arglist]
  (.invoke (.getDeclaredMethod
             (class obj) (name method) nil)
           obj (into-array arglist)))
(dynamic-invoke url host [])
