If I understand correctly it could be implemented with the following
change to Reflector.java:
static Object boxArg(Class paramType, Object arg){
if(paramType.isInterface() && arg instanceof IFn)
return makeAProxy( findMethodMatch( paramType, arg ),
arg );
Which would then allow us to instead of using proxy:
> (.addMouseListener
> (proxy [MouseAdapter] []
> (mouseClicked [event]
> (if (= 2 (.getClickCount event))
> (display-details (.locationToIndex (.getPoint event)))))))
Write it using a function which will discover what interface/method to
create a proxy for:
(.addMouseListener
#(if (= 2 (.getClickCount %))
(display-details (-> % .getPoint .locationToIndex)))
something)
The alternative solution for doing that if we are willing to create a
macro or helper function:
(defmacro add-action-listener
"Attaches an ActionListener to a Component"
[#^java.awt.Component obj, evt & body]
`(.addActionListener
~obj (proxy [java.awt.event.ActionListener] []
(actionPerformed [~evt] ~...@body))))
(add-action-listener something evt
(if (= 2 (.getClickCount evt))
(display-details (-> evt .getPoint .locationToIndex))))
The only difference being of course that you'd need a separate helper
for all the different interfaces want to proxy, and would have to
explicitly choose which interface the function implements. I don't
have enough experience to know of how many anonymous single function
interface proxies are useful.
