Event Generation

The Generate  class extends Atom which means that event generation terminates instantaneously. Generating an event in a machine calls the machine newMove method to indicate that something new happens in the system; thus, instructions waiting for the event (see next 5.3) will have the possibility to see it as present during the current instant.

public class Generate extends Atom
  private String eventName;

  public Generate(String eventName){ 
    this.eventName = eventName; 

  final public boolean equals(Instruction inst){
    return  super.equals(inst) && 

  final public String toString(){ 
    return "generate " + eventName; 

  final protected void action(Machine machine){
    Event event = machine.getEvent(eventName);
