A quick overview of Object-oriented program design, with special regard for operating-system development, this book will be of the greatest interest to those developers who are working with Taligent and its operating partners, as well as many other C++ programmers who are interested in a provocative summary of good OOP techniques.

Chapters include:

• Architectural goals
• Object-oriented architecture
• All interfaces are expressed through objects
• Commonality is managed through inheritance
• Objects are leveraged wherever possible
• Frameworks provide the foundation
• Let resources find you
• Putting it all together
• Reflect the client’s view
• Let resources find you
• Express all interfaces through objects
• Preserve class invariants
• Object-oriented design with C++
• C++ doesn’t express full object interface
• C++ requires definition of special member functions
• Use type inheritance to share protocol
• Useimplementation inheritance to override behavior
• Design the interfaces between the base and derived classes
• Guarantee use of derived classes as arguments
• Implement full protocol in derived classes
• Preserve semantics in a derived class
• Avoid deep nesting in lightweight objects
• Be aware of problems with virtual bases
• Avoid multiple occurrences of a base
• Design performance in
• Conduct performance analysis
• Perform controlled experiments
