Question

What principles do you generally follow when doing class design?

Answer 1

SOLID principles and Liskov's pattern, along with Single responsibility pattern.

Answer 2

As mentioned above, some of the fundamental Object Oriented Design principles are OCP, LSP, DIP and ISP.

An excellent overview of these by Robert C. Martin (of Object Mentor) is available here: OOD Principles and Patterns

Answer 3

The S.O.L.I.D. principles.
Or at least I try not to steer away too much from them.

Answer 4

I usually try to fit the class into one of the oo design patterns.

Answer 5

The "Resource Acquisition Is Initialization" paradigm is handy, particularly when writing in C++ and dealing with operating system resources (file handles, ports, etc.).

A key benefit of this approach is that an object, once created, is "complete" - there is no need for two-phase initialization and no possibility of partially-initialized objects.

Answer 6

loosely coupled, highly cohesive.

Composition over inheritance.
