code: private Map<Key, Array> store(Class clazz) {
  	Method[] methods = clazz.getMethods();
  	Map<Key, Array> methodsMap = new ConcurrentHashMap<Key, Array>();
  	for (int i = 0; i < methods.length; i++) {
  	    storeMethod(methods[i], methodsMap);
  
  	}
  	map.put(clazz, methodsMap);
  	return methodsMap;
      }
