inheritance

  • The theory behind inheritance is that the world is best represented by a hierarchy

    • this hierarchy will help with code reuse

When to use

  • When not create wide or deep object hierachies

  • Ideally, should have one level where subclasses are the leafs of the superclass

Why bad?

  • leads to more brittle systems and defects

    • told to favour composition over inheritance as getting inheritance correct is difficult

  • A lot of patterns were created to overcome the usage of inheritance
