Component
Appearance
All functionality in Advanced Computers is implemented via components. Components are represented by Lua's Userdata (short: UD) type, which in our case are represented by Java objects which are provided by items/blocks.
Components are generally accessed by calling components:getFirst("yourComponentType"), for more information see Computer and the wiki page of any other item/block that provides a component. The components field is a global field injected into every computer Lua instance during initialization.
