getWalkLength

public int getWalkLength()

appendWalkTo

public void appendWalkTo(List<State> walk)

getLoginContext

public LoginContext getLoginContext()

stateAlreadyVisited

public boolean stateAlreadyVisited(State state)

recordFailedState

public void recordFailedState(State state,
                              StateTransitionResult stateTransitionResult)

getFailedStates

public Map<State,StateTransitionResult> getFailedStates()

wouldCauseCycle

public boolean wouldCauseCycle(StateDescriptorGraph.GraphVertex<State> successorStateVertex)

Check if the way to the final state via the given successor state that would loop, i.e., lead over the initial state and thus from a cycle.

Parameters:

successorStateVertex - the successor state to use on the way.

Returns:

true if it would loop, false otherwise.
