How do I implement a Java interface in Clojure

Question

How do I create a Clojure object that implements this interface and then gets called from Java code?

public interface Doer {
   public String doSomethin(Stri         


        

Answer 1

If doSomethin() is defined in your interface, you should not mention it in :methods. Quote from http://clojuredocs.org/clojure_core/clojure.core/gen-class:

:methods [ [name [param-types] return-type], ...]
The generated class automatically defines all of the non-private
methods of its superclasses/interfaces. This parameter can be used
to specify the signatures of additional methods of the generated
class. Static methods can be specified with ^{:static true} in the
signature's metadata. Do not repeat superclass/interface signatures
here.
