Method Detail

getHypothesisModel

public net.automatalib.automaton.transducer.MealyMachine<?,I,?,O> getHypothesisModel()

stateProperty

protected Void stateProperty(ObservationTable<I,O> table,
                             Row<I> stateRow)

Description copied from class: AbstractAutomatonLStar

Derives a state property from the corresponding row.

Specified by:

stateProperty in class AbstractAutomatonLStar<net.automatalib.automaton.transducer.MealyMachine<?,I,?,O>,I,O,Integer,net.automatalib.automaton.impl.CompactTransition<O>,Void,O,net.automatalib.automaton.transducer.impl.CompactMealy<I,O>>

Parameters:

table - the current observation table

stateRow - the row for which the state is created

Returns:

the state property of the corresponding state

transitionProperty

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

Description copied from class: AbstractAutomatonLStar

Derives a transition property from the corresponding transition.

Note that 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.automaton.transducer.MealyMachine<?,I,?,O>,I,O,Integer,net.automatalib.automaton.impl.CompactTransition<O>,Void,O,net.automatalib.automaton.transducer.impl.CompactMealy<I,O>>

Parameters:

table - the observation table

stateRow - the row for the source state

inputIdx - the index of the input symbol to consider

Returns:

the transition property of the corresponding transition

addAlphabetSymbol

public void addAlphabetSymbol(I symbol)

Specified by:

addAlphabetSymbol in interface net.automatalib.alphabet.SupportsGrowingAlphabet<I>

Overrides:

addAlphabetSymbol in class AbstractAutomatonLStar<net.automatalib.automaton.transducer.MealyMachine<?,I,?,O>,I,O,Integer,net.automatalib.automaton.impl.CompactTransition<O>,Void,O,net.automatalib.automaton.transducer.impl.CompactMealy<I,O>>

hypothesisOutput

protected net.automatalib.automaton.concept.SuffixOutput<I,O> hypothesisOutput()

Specified by:
