Method Detail

updateInternalHypothesis

protected void updateInternalHypothesis()

Description copied from class: AbstractAutomatonLStar

Performs the L*-style hypothesis construction. For creating states and transitions, the AbstractAutomatonLStar.stateProperty(Row) and AbstractAutomatonLStar.transitionProperty(Row, int) methods are used to derive the respective properties.

Overrides:

updateInternalHypothesis in class AbstractAutomatonLStar<net.automatalib.automata.transout.MealyMachine<?,I,?,O>,I,net.automatalib.words.Word<O>,Integer,net.automatalib.automata.transout.impl.compact.CompactMealyTransition<O>,Void,O,net.automatalib.automata.transout.impl.compact.CompactMealy<I,O>>

stateProperty

protected Void stateProperty(Row<I> stateRow)

Description copied from class: AbstractAutomatonLStar

Derives a state property from the corresponding row.

Specified by:

stateProperty in class AbstractAutomatonLStar<net.automatalib.automata.transout.MealyMachine<?,I,?,O>,I,net.automatalib.words.Word<O>,Integer,net.automatalib.automata.transout.impl.compact.CompactMealyTransition<O>,Void,O,net.automatalib.automata.transout.impl.compact.CompactMealy<I,O>>

Parameters:

stateRow - the row for which the state is created

Returns:

the state property of the corresponding state

transitionProperty

protected O transitionProperty(Row<I> stateRow,
                   int inputIdx)

Description copied from class: AbstractAutomatonLStar

Derives a transition property from the corresponding transition.

N.B.: Not the transition row is passed to this method, but the row for the outgoing state. The transition row can be retrieved using Row.getSuccessor(int).

Specified by:

transitionProperty in class AbstractAutomatonLStar<net.automatalib.automata.transout.MealyMachine<?,I,?,O>,I,net.automatalib.words.Word<O>,Integer,net.automatalib.automata.transout.impl.compact.CompactMealyTransition<O>,Void,O,net.automatalib.automata.transout.impl.compact.CompactMealy<I,O>>

Parameters:

stateRow - the row for the source state

inputIdx - the index of the input symbol to consider

Returns:

the transition property of the corresponding transition

initialSuffixes

protected List<net.automatalib.words.Word<I>> initialSuffixes()

Description copied from class: AbstractLStar

Returns the list of initial suffixes which are used to initialize the table.

Overrides:

initialSuffixes in class ExtensibleAutomatonLStar<net.automatalib.automata.transout.MealyMachine<?,I,?,O>,I,net.automatalib.words.Word<O>,Integer,net.automatalib.automata.transout.impl.compact.CompactMealyTransition<O>,Void,O,net.automatalib.automata.transout.impl.compact.CompactMealy<I,O>>

Returns:

the list of initial suffixes.

updateOutputs

protected void updateOutputs()

exposeInternalHypothesis

protected net.automatalib.automata.transout.MealyMachine<?,I,?,O> exposeInternalHypothesis()

Specified by:

exposeInternalHypothesis in class AbstractAutomatonLStar<net.automatalib.automata.transout.MealyMachine<?,I,?,O>,I,net.automatalib.words.Word<O>,Integer,net.automatalib.automata.transout.impl.compact.CompactMealyTransition<O>,Void,O,net.automatalib.automata.transout.impl.compact.CompactMealy<I,O>>

hypothesisOutput

protected net.automatalib.automata.concepts.SuffixOutput<I,net.automatalib.words.Word<O>> hypothesisOutput()

Specified by:

hypothesisOutput in class AbstractLStar<net.automatalib.automata.transout.MealyMachine<?,I,?,O>,I,net.automatalib.words.Word<O>>
