| Chain of Responsibility |
|
Part 1: How does the Chain of Responsibility pattern differ from the Decorator pattern
or from a linked list?
Part 2: Is it helpful to look at patterns from a structural perspective? In other words, if you see how a set of patterns are the same in terms of how they are programmed, does that help you to understand when to apply them to a design? |
| Memento |
| The authors write that the "Caretaker" participant never operates on or examines the contents of a memento. Can you consider a case where a Caretaker would infact need to know the identity of a memento and thus need the ability to examine or query the contents of that memento? Would this break something in the pattern? |
