I'd like to use reflection to get a method of a Java object from Clojure. One of the argument types is a Java primitive and I don't know how to refer to them from Clojure. For example, say I wante...

I have come across the @JvmSynthetic annotation in kotlin-stdlib, and I'm wondering what it is for, but, unfortunately, it is undocumented. (UPD: it was at that moment) As far as I understand, app...

This following declaration is legal in Kotlin. fun foo(): String = "foo_1" fun <T> foo(): T = "foo_2" as T As bytecode we are getting: public final static foo()Ljava/lang/String; // sign...

For the purposes of interoperability with Java, I need a class that has a nullary constructor that performs initialization. Objects of this class need to have something resembling mutable java fiel...

I'm attempting to use deftype (from the bleeding-edge clojure 1.2 branch) to create a java class that implements the java Servlet interface. I would expect the code below to compile (even though it...

I am trying to wrap a Java library with a Clojure binding. One particular class in the Java library defines a bunch of static final constants, for example: class Foo { public static final int BAR...
