Using Java Class Extension Library for Data-Oriented Programming - Part 2
- This article presents class extensions using Java Class Extension library for data-oriented programming to effectively separate data from domain-specific logic in a more functional style.
- The article addresses a scenario of building a warehouse application designed to handle the shipping of various Items when implementing shipping logic for each item.
- The approach to keep Items primarily as data classes and separate domain-specific logic was introduced in the first article using static class extensions.
- The article provides an alternative way of defining and implementing extensions using new dynamic Java Class Extension in a functional style.
- Through the shared builder, the article discusses how to mimic class extensions to specify an extension using a set of lambda operations.
- The article shows how to find an extension and call its methods for both a single item and a collection of items.
- The article concludes that the Java Class Extension library provides a valuable alternative for class extensions with just a little more verbose code and a little more complex implementation.
- Inheritance support, caching and limitations of DynamicClassExtension were also discussed in the article.
- By leveraging this library, developers can maintain a clean separation between data classes and domain-specific logic while adhering to OOP principles.
- This results in a flexible and extensible codebase that enhances maintainability and reduces errors.
