code: public V get(K key) {
      V value = _cacheImpl.get(key);
      _requests.incrementAndGet();
      if (value == null) {
        value = _missHandler.load(key);
        _cacheImpl.put(key, value);
        _misses.incrementAndGet();
      } else {
        _hits.incrementAndGet();
      }
      return value;
    }
docs: This will get a specific entry, it will call the missHandler if it is not found.
  
  @param key the object to find
  @return the found object (may be null)
