How does the Proxy design pattern differ from the Decorator design pattern?
- Proxy adds new behavior; Decorator manages object's responsibilities
- Proxy controls access to an object; Decorator adds functionality
- Proxy does not modify object; Decorator modifies object's behavior
- Proxy modifies existing behavior; Decorator adds new behavior
The Proxy design pattern acts as a surrogate or placeholder for another object and controls access to it. On the other hand, the Decorator pattern dynamically adds new functionality to an object without altering its structure. Proxy focuses on controlling access, while Decorator focuses on adding responsibilities. Understanding these distinctions is crucial when deciding which pattern to use in a given context.
