Here's an example illustrating some of the basics about classes.

Until more documentation is here, for examples of using classes, see the classes-.boo files under tests/testcases/integration/types, as well as super-.boo, abstract-.boo, interfaces-.boo, baseclass-.boo, innerclasses-.boo, fields-.boo, and properties-.boo.

interface IAnimal:
    Name as string:
        get

    Legs as int:
        get

    def Eat(food)

class Dog(IAnimal):
    Name:
        get:
            return "Canine"

    Legs:
        get:
            return 4

    def Eat(food):
         if food isa IPlant:
                Speak()

    def Speak():
         print "bark!"

interface IPlant:
    pass

class Rice(IPlant):
    pass

//////////////////////////

d = Dog()

print "$(d.Name) has $(d.Legs) legs."

r = Rice()
d.Eat(r)
