Access non-static enum in Clojure

Let's say there is a Java class with a non-static enum field as below.
package com.example;

public class Encrypter {

public enum KeyPlacement {

private KeyPlacement keyPlacement;

public KeyPlacement getKeyPlacement() {
return this.keyPlacement;

public void setKeyPlacement(final KeyPlacement newKeyPlacement) {
this.keyPlacement = newKeyPlacement;

Setting keyPlacement value from Clojure can be done as follows.
(ns core
(:import [com.example Encrypter Encrypter$KeyPlacement]))

(doto (Encrypter.)
(.setKeyPlacement Encrypter$KeyPlacement/INLINE))

When compiling the above source, inner classes, enums etc. gets generated with $ appended as Encrypter$KeyPlacement. So we can import those and access them from Clojure.
