Controller

class Controller

A Controller is a reusable control-behaviour type - the unit that defines the commands, states, transitions, interlocks and messages for one kind of device or function. It is instantiated many times as ControllerInstances in the tree and exposes its behaviour through a public interface, a per-instance interface and a private internal interface. A project controller usually extends a library base controller and adds only its specific behaviour.

Create a controller

  • By right-clicking on a package you enter the context menu.
  • Open resource assist om3koevv
  • A new controller is created by selecting the controller element.

The controller corresponds to a type that is instantiated. Therefore, the name should be capitalized.
