While functional decorators remain popular among many Pythonistas, class-based decorators present alternative ways to achieve similar goals. Leveraging the advantages offered by classes enables improved code readability and increased design possibilities.
We’ll walk you through building and employing class-based decorators so that you too may benefit from this approach.
Understanding Class-Based Decorators
At heart, class-based decorators involve writing decorators based on classes rather than standalone functions. These decorators gain abilities typical of objects, including inheritance, polymorphism, and encapsulation.
Moreover, class-based decorators often lead to clearer implementations and facilitate future enhancements compared to their functional counterparts.
Building a Basic Class-Based Decorator
Consider a basic decorator meant to measure a function’s runtime performance. Instead of implementing it as a regular function, we’d introduce a dedicated Timer…
