The Final Keyword
The final
keyword plays a crucial role in defining classes and controlling inheritance hierarchies. It provides developers with a powerful mechanism to restrict certain aspects of class design.
The usage of final keyword
When a class is declared as final
, it indicates that the class cannot be subclassed further. In other words, it serves as the end point of the inheritance hierarchy, disallowing from deriving it.
Example.cpp
This feature is especially valuable when you aim to restrict the modification or extension of a specific class, or when you prefer utilizing your class using composition rather than inheritance. There is also other benefits to using it.
Enhanced Design Control | Marking classes as final enables precise control over the inheritance hierarchy, preventing unintended modifications or extensions. |
Code Safety | Utilizing final enhances code safety by enforcing design decisions and reducing the risk of introducing bugs or inconsistencies through subclassing. |
Performance Optimization | Compiler optimizations can be more effectively applied when certain classes are marked as final , potentially leading to improved runtime performance. |
