Posting this for a very similar reason to my Cursor Affordance post. I already know what the Substitution Principle is, I just did not know what it was called.
By definition “the principle defines that objects of a superclass shall be replaceable with objects of its subclasses without breaking the application”
Let’s run some examples.
Superclass: Animal
Subclasses: Dog, Cat, Turtle, Moose
Superclass: Projectile
Subclasses: Arrow, Missile, Spear, Bullet
Superclass: DrinkingVessel
Subclasses: Mug, Glass, DrinkingHorn, Beaker
Superclass: Monster
Subclasses: Gobblin, Cyclops, Dragon, Golem
