Structural Design Patterns in Modern C++ - Adding the Abstract Decorator Class in Stream Class Hierarchies

The video tutorial explains the transition from inheritance to composition in stream classes, highlighting the limitations of the current structure. It introduces the decorator pattern as a solution to enhance flexibility and functionality, allowing for the combination of features like buffering, encryption, and compression. The tutorial provides a detailed walkthrough of implementing the decorator pattern, including creating new decorators and managing features dynamically at runtime.
