1. The Template Method pattern encapsulates an algorithm’s outline in a base class while leaving some parts of that algorithm open for modification by its subclasses.
2. The Chain of Responsibility pattern divides a larger problem into small pieces (handlers). Each piece is self-governed, while the chain’s existence is abstracted from its consumers.
3. False; you can create as many abstract (required) or virtual (optional) extension points (hooks) as you need.
4. Yes, there is no reason not to.
5. No, there isn’t a specific limit of 32 handlers in a Chain of Responsibility pattern. However, in practice, the number of handlers is limited by system resources and performance considerations, similar to other coding constructs.
6. In the stricter sense, a handler must either process the message or defer it to the next handler in the chain. However, allowing more than one handler to process a message creates a pipeline, which opens a lot of...
