SOLID Principles in Chromium Blink Compositor

The provided source is an in-depth analysis of the Chromium Blink cc Compositor module's architecture, viewed through the lens of the SOLID software design principles. This technical document, aimed at C++ engineers, systematically examines how the module adheres to or deviates from the principles of Single Responsibility (SRP), detailing how components like property trees and scheduling classes isolate concerns; Open/Closed (OCP), explaining how polymorphism allows for new layer types and rasterization strategies without modifying core code; Liskov Substitution (LSP), assuring that layer subclasses and interfaces are correctly substitutable; Interface Segregation (ISP), demonstrating the use of many small, focused client interfaces to minimize dependencies; and finally, Dependency Inversion (DIP), which highlights the use of abstract interfaces to decouple the compositor from both the higher-level Blink engine and the low-level Viz/GPU display details. Overall, the text praises the compositor's modularity, testability, and flexibility achieved through careful adherence to these object-oriented guidelines.
