Method Detail

lookup

public boolean lookup(Word<? extends I> word,
                      List<? super O> output)

Description copied from interface: IncrementalMealyBuilder

Retrieves the output word for the given input word. If no definitive information for the input word exists, the output for the longest known prefix will be returned.

Parameters:

word - the input word

output - a consumer for constructing the output word

Returns:

true if the information contained was complete (in this case, word.length() == output.size() will hold), false otherwise.

insert

public void insert(Word<? extends I> input,
                   Word<? extends O> outputWord)
            throws ConflictException

Description copied from interface: IncrementalMealyBuilder

Incorporates a pair of input/output words into the stored information.

Parameters:

input - the input word

outputWord - the corresponding output word

Throws:

ConflictException - if this information conflicts with information already stored

asGraph

public IncrementalMealyTreeBuilder.GraphView asGraph()

Description copied from interface: IncrementalConstruction

Retrieves a graph view of the current state of the construction. The graph model should be backed by the construction, i.e., subsequent changes will be reflected in the graph model.

Returns:

a graph view on the current state of the construction

asTransitionSystem

public IncrementalMealyTreeBuilder.TransitionSystemView asTransitionSystem()

Description copied from interface: IncrementalConstruction

Retrieves a transition system view of the current state of the construction. The transition system model should be backed by the construction, i.e., subsequent changes will be reflected in the transition system.

Returns:

a transition system view on the current state of the construction

findSeparatingWord

public Word<I> findSeparatingWord(MealyMachine<?,I,?,O> target,
                                  Collection<? extends I> inputs,
                                  boolean omitUndefined)

Description copied from interface: IncrementalConstruction

Checks the current state of the construction against a given target model, and returns a word exposing a difference if there is one.

Parameters:

target - the target automaton model

inputs - the set of input symbols to consider

omitUndefined - if this is set to true, then undefined transitions in the target model will be interpreted as "unspecified/don't know" and omitted in the equivalence test. Otherwise, they will be interpreted in the usual manner (e.g., non-accepting sink in case of DFAs).

Returns:

a separating word, or null if no difference could be found.

hasDefinitiveInformation

public boolean hasDefinitiveInformation(Word<? extends I> word)

Description copied from interface: IncrementalConstruction

Checks whether this class has definitive information about a given word.

Specified by:

hasDefinitiveInformation in interface IncrementalConstruction<MealyMachine<?,I,?,O>,I>

Overrides:

hasDefinitiveInformation in class AbstractIncrementalMealyBuilder<I,O>

Parameters:

word - the word

Returns:

true if this class has definitive information about the word, false otherwise.
