Inheritance vs Composition#
This site has a nice little summary of Inheritance vs Composition.
Class Inheritance should be used only if instances of the new class can be used in all situations where the existing class can be used. Class Inheritance not inappropriate if the subclass needs to stub out behaviour implemented by the superclass. Use Object Composition if instances of the new class do not require the protocol of the superclass.
