Examples of java.util.IdentityHashMap.clone()

java.util.IdentityHashMap.clone()
Returns a shallow copy of this identity hash map: the keys and values themselves are not cloned. @return a shallow copy of this map

    Collection values = map.values();
    assertEquals("values() does not work", 
        "value", values.iterator().next());
    assertEquals("keySet() does not work", 
        "key", keys.iterator().next());
    AbstractMap map2 = (AbstractMap) map.clone();
    map2.put("key", "value2");
    Collection values2 = map2.values();
    assertTrue("values() is identical", values2 != values);
    // values() and keySet() on the cloned() map should be different
    assertEquals("values() was not cloned",
