Add marker Interfaces for defrecords and deftypes plus boolean test fns

Enhancement Minor Open Unresolved Unassigned Assembla Importer Mon, 5 Jul 2010 09:58:00 -0500 Fri, 1 Mar 2013 09:41:09 -0600 Release 1.6 0 4 <p>Converted from <a href="http://www.assembla.com/spaces/clojure/tickets/394">http://www.assembla.com/spaces/clojure/tickets/394</a></p> <p>As of Clojure 1.3, there are marker interfaces named clojure.lang.IType and clojure.lang.IRecord. You can use instance? with those interfaces. I'm not sure if they're actually documented for public use, but they seem to work as expected in 1.3 and 1.4. If you want record?, you can try this:</p> <p>(defn record? <span class="error">&#91;rec&#93;</span> (instance? clojure.lang.IRecord rec))</p> <p>See attached code and test. I'm unsure as to whether or not the location of the tests and predicates make sense. Please let me know if I should move them elsewhere.</p> Global Rank Patch Code and Test
