Topic-Id: DESIGN
General design rules.
Contents
Summary
No Cyclic Dependencies (CyclDep)
Avoid cyclic dependencies.
Dependency Inversion Principle (DIP)
Use the dependency inversion principle. Prefer to define functionality in abstract interfaces and to inherit from them. Avoid state in abstract classes.
No Premature Generalization (PremGen)
As a rule of thumb, don't generalize before the second occurrence and no later than the third.
Global Data Initialization (GlobInit)
Avoid cross module dependencies when initializing global data. Never let a global object's initialization depend on another global object in a different compilation unit.
Avoid Global Data (NoGlob)
Minimize the use of global data. For objects in global scope that are meant to be local to the implementation of a class use an anonymous namespace.
