IState (jrexx Developer Documentation)

Interface IState

public interface IState

IState is the epsilon enclosure of one or more IStatePro. The epsilon enclosure of an IStatePro are the IStatePro itself and all states that are reachable through epsilon transitions (see IStatePro.addTransition) beginning with that IStatePro.
You can get an epsilon enclosure of an IStatePro startState manually by this code:


 
  final IStatePro startState;
 
  final StateProSet epsilonClosure = new StateProSet(startState);
 
  final Iterator it = states.iterator();
 
  for (IStatePro state=it.next(); state!=null; state=it.next()) {
 
    IStatePro.ITransition[] transitions = state.getETransitions();
 
    for (int i=0; i transitions.length; ++i) {
 
      epsilonClosure.add(transitions[i].getToState());
 
    }
 
  }

Method Detail

public StateProSet getAllReachableStates()

Returns all states that are reachable from this state through it's transitions and so on.
important: this state is only element of the returned set, if it is an element of a loop

Returns: all reachable states as a set

public boolean isFinal()

public IState next(char ch)

returns the IState of all IStatePro that are reachable from this IState with a character ch.

Parameters: ch

Returns:
