Method Detail

getAccessSequence

net.automatalib.word.Word<I> getAccessSequence(I procedure)

Returns an access sequence for the given procedure.

Parameters:

procedure - the call symbol that identifies the procedure

Returns:

the access sequence for the given procedure

getTerminatingSequence

net.automatalib.word.Word<I> getTerminatingSequence(I procedure)

Returns a terminating sequence for the given procedure.

Parameters:

procedure - the call symbol that identifies the procedure

Returns:

the terminating sequence for the given procedure

scanCounterexample

net.automatalib.common.util.Pair<Set<I>,Set<I>> scanCounterexample(DefaultQuery<I,net.automatalib.word.Word<O>> counterexample)

Extracts from a positive counterexample (potentially new) access sequences and terminating sequences.

Parameters:

counterexample - the counterexample

Returns:

a Pair of Sets of procedures (identified by their respective call symbols) for which new access and terminating sequences could be extracted and for which previously none of the sequences were available.

scanProcedures

Set<I> scanProcedures(Map<I,? extends net.automatalib.automaton.transducer.MealyMachine<?,SymbolWrapper<I>,?,O>> procedures,
                      Map<I,? extends AccessSequenceTransformer<SymbolWrapper<I>>> providers,
                      Collection<SymbolWrapper<I>> inputs)

Scans a set of (hypothesis) procedures in order to potentially extract new access sequences and terminating sequences.

Parameters:

procedures - a Map from call symbols to the respective procedural (hypothesis) models

providers - a Map from call symbols to AccessSequenceTransformers

inputs - a Collection of input symbols which should be used for finding new access sequences, terminating sequences, and return sequences

Returns:

a Set of procedures (identified by their respective call symbols) for which terminating sequences could be extracted and for which previously no such sequences were available.
