The simple sequence:
  • InitialNode (in fact optional here).
  • A simple OpaqueAction to print a connection message.
  • ReadSelfAction to get at context Controller object.
  • ReadStructuralFeatureAction to get at its dialer:Dialer
  • ReadStructuralFeatureAction to get at the number:Number
  • A CallOperationAction invokes print() on the Number, which just prints the current accumulated dialed digits.
  • FinalNode

We look at the StateMachine for the Dialer next
