What are the common mistakes in the decorator pattern?
An example of an AI chatbot conversation about common mistakes in the decorator pattern.
What are the common mistakes in the decorator pattern?
Some common mistakes include not using the decorator correctly, violating the single responsibility principle, and not considering the order of decorators.
Can you explain how violating the single responsibility principle happens?
Sure! It happens when a decorator is responsible for multiple functionalities, making it harder to maintain and test.
What about the order of decorators? Why is it important?
The order of decorators matters because it affects the behavior of the wrapped object. The outermost decorator is applied first.
Can you give an example of a mistake in the order of decorators?
Certainly! If you have a logging decorator and a validation decorator, applying logging first may log invalid data, which is not ideal.
