public class stepListener

extends Object

implements ActionListener

stepListener(MachineFrame)

The listener responds to clicks on the Step button.

actionPerformed(ActionEvent)

 public stepListener(MachineFrame p)

The listener responds to clicks on the Step button. It calls the step method in the machine with a default visitor that executes instructions. It needs access to the parent frame to report errors that might happen during the execution of the command. Since the execution of the machine command might hang waiting for input or might diverge, it runs within a newly created thread so that the GUI can still respond to the user.
