  About Lua

  # Lua Classes With Metatable
  Lua has matured from an application extension language into a wonderfully flexible scripting language. Lua 5.0 is not an object oriented language like Java or Ruby. Instead, Lua gives you the ability to implement classes however you wish. This is both a bonus and a bane. Power users love the freedom, but newbies are sometimes baffled.

  About Gideros

  @atilim said :
  in fact, gideros.class (Note : now deprecated, use Core.class instead) is a simple Lua OO mechanism. Except inheritance, Its implementation is very similar to the code below. You can directly use this instead of inheriting from EventDispatcher:

  LinkedList = {} LinkedList.__index = LinkedList   function LinkedList.new(...) local self = setmetatable({}, LinkedList) if self.init ~= nil and type(self.init) == "function" then self:init(...) end return self end   -- your actual LinkedList implementation starts from here   function LinkedList:init()   end
