A Flyweight Pattern says that just "to reuse already existing similar kind of objects by storing them and create new object when no matching object is found".. Each time an object is requested, the factory looks up the object in order to check if it's already been created. Flyweight. Using the Flyweight pattern you write the validators once and you can easily add more validators through the development of your code. The fog lifts, revealing a majestic old growth forest.
