functional programming - Does a Clojure proxy always invoke super.method()? -

Existing methods should be overridden by using fns passed to a proxy or they super.method () ?

In the following code, RequestHandler.get () is applied with the proxy get [] .

see: http://github.com/paulosuzart/JTornado (ns org.ctornadoweb) (import '(org.jtornodgeeb web $ request handler)) (import' (org.jtornadoweb HttpServer Web Get $ [Handler (Proxy [Web $ Request Handler] [] ([] (.write "hi CLJ")) (Post [] (Post "Post"))) (.listen (HttpServer) (.add (web. App.) "/" (Class myHandler) false false false) 8089))

Compiled / succession version is the same:

 ; A JTornado HTTP Server and a Sample RequestHandler Begins; Bit verbose due to compilation instructions The recommendation is to generate; To hide this, the set of macros (ns org.ctornadoweb;) compiles and applies a static main method to start the server: (import: prefix "server-")) (gene-class: name org.ctornadoweb.myhandler : Extends org.jtornadoweb.Web $ requestHandler: prefix "doo" (def-dot-dot [this] "HTTP handles the GET method" (writes "Hello Closer") (deferring-post [this] "HTTP Post method handles "(.write (.getArgument" name "" default "false)) (server-main [defn defn]" main method "(.listen (org.jto) Rnadoweb.HttpServer (.add (org.jtornadoweb.Web $ app.) "/" Org.ctornadoweb.MyHandler) false false false) 8089); (compilation 'org.ctornadoweb)  

The trace shows that the proxy is being used and then super.get, which is a default exception (throws).

  HTTP 405: method is not allowed .jtornadoweb.Web $ RequestHandler.get (Web .Java 72) at Rg.ctornadoweb.proxy $ org.jtornadoweb.Web $ RequestHandler $ 0.get (unknown source)  

I close Finding a few words about the actual behavior of the proxy Have someone tried to help this? No, super method will not be automatically asked, although you obviously call it

.

The following test cases should show work:

  user = & gt; (Def foo (proxy [java.util.ArrayList] [] (pronounced [] (println "not clearing")) # # user / foo user = & gt; (.size foo) 0user => (. Add foo "hi") real user => (.add foo "bye") real user => (.size foo) 2 user => (.clear foo) zero user => (. Isize foo) 2  

If was being called super.clear () , the size will appear as 0.
