What is the Template Method Pattern in architecture?

The Template Method Pattern is a design pattern that defines the skeleton of an algorithm in a method, deferring some steps to subclasses. It allows subclasses to redefine certain steps of an algorithm without changing its structure.

Can you give me an example of where this pattern is used?

Sure! A common example is in a data processing application where the main algorithm for processing data is defined in a base class, but specific data formats (like CSV, JSON) are handled in subclasses.

What are the benefits of using this pattern?

The benefits include code reusability, easier maintenance, and the ability to enforce a consistent algorithm structure while allowing flexibility in specific implementations.

Are there any drawbacks to using the Template Method Pattern?

Yes, potential drawbacks include increased complexity and the risk of creating a rigid structure that may not accommodate future changes easily.
