http://labs.carrotsearch.com/download/hppc/0.4.1/api/com/carrotsearch/hppc/ObjectObjectOpenHashMap.html#forEach(T) public <T extends BiConsumer<? super K,? super V>> T forEach(T sink) funny as it looks, it allows the caller to create an anonymous class instance and get at its methods/ fields in a call chain. int counted = map.forEach(new BiConsumer<X,Y>() { public int counter; // the rest of the implementation... }).counter; Just a thought.
