Documentation

Simple class

local SimpleClass = class("SimpleClass")

-- constructor, automatically called
function SimpleClass:initialize()
end

-- definition of a class method
function SimpleClass:classMethod()
end

-- class instancing and method calling
local instance = SimpleClass:new()
instance:classMethod()

Class inheritance and invoking super methods.

-- definition of a super class
local SuperClass = class("SuperClass")

function SuperClass:classMethod()
end

-- definition of a derived class
local SimpleClass = class("SimpleClass", SuperClass)

function SimpleClass:classMethod()
	self.super:classMethod()
end

Mixins / Multiple inheritance

You can actually have an unlimited number of inheritances

-- definition of a mixin class
local Mixin = class("Mixin")

function Mixin:randomFunction()
end

-- definition of a class that derives off of another class and has a mixin.
local SimpleClass = class("SimpleClass", SuperClass, Mixin)

function SimpleClass:classMethod()
	self.super:classMethod()
end
