Interface IState

All Known Implementing Classes:

SAutomaton.State

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 StateProSet.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());
}

StateProSet	getAllReachableStates() Returns all states that are reachable from this state through it's transitions and so on.
boolean	isFinal()
IState	next(char ch) returns the IState of all IStatePro that are reachable from this IState with a character ch.

Method Detail

isFinal

boolean isFinal()

next

IState next(char ch)

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

Parameters:

ch -

Returns:

getAllReachableStates

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
