[ Gamma et al] Flyweight pattern applies in situations when different identical objects have some common state that is shared among them. The state of flyweight objects is termed as intrinsic (common Pattern. flyweight Pattern. Matt Klein. Decorator Pattern. Intent. Attach Additional responsibilities to an object by dynamically.
