4.8 Conclusion
5 Information Hiding (and Leakage)
5.1 Information hiding
5.2 Information leakage
5.3 Temporal decomposition
5.4 Example: HTTP server
5.5 Example: too many classes
5.6 Example: HTTP parameter handling
5.7 Example: defaults in HTTP responses
5.8 Information hiding within a class
5.9 Taking it too far
5.10 Conclusion
6 General-Purpose Modules are Deeper
6.1 Make classes somewhat general-purpose
6.2 Example: storing text for an editor
6.3 A more general-purpose API
6.4 Generality leads to better information hiding
6.5 Questions to ask yourself
6.6 Conclusion
7 Different Layer, Different Abstraction
7.1 Pass-through methods
7.2 When is interface duplication OK?
7.3 Decorators
7.4 Interface versus implementation
7.5 Pass-through variables
7.6 Conclusion
8 Pull Complexity Downwards
8.1 Example: editor text class
8.2 Example: configuration parameters
