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, 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)
