Method Detail

getAccessSequence

public Word<I> getAccessSequence(I procedure)

Description copied from interface: ATManager

Returns an access sequence for the given procedure.

Specified by:

getAccessSequence in interface ATManager<I,O>

Parameters:

procedure - the call symbol that identifies the procedure

Returns:

the access sequence for the given procedure

getTerminatingSequence

public Word<I> getTerminatingSequence(I procedure)

Description copied from interface: ATManager

Returns a terminating sequence for the given procedure.

Specified by:

getTerminatingSequence in interface ATManager<I,O>

Parameters:

procedure - the call symbol that identifies the procedure

Returns:

the terminating sequence for the given procedure

scanCounterexample

public Pair<Set<I>,Set<I>> scanCounterexample(DefaultQuery<I,Word<O>> counterexample)

Description copied from interface: ATManager

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

Specified by:

scanCounterexample in interface ATManager<I,O>

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

public Set<I> scanProcedures(Map<I,? extends MealyMachine<?,SymbolWrapper<I>,?,O>> procedures,
                             Map<I,? extends AccessSequenceTransformer<SymbolWrapper<I>>> providers,
                             Collection<SymbolWrapper<I>> inputs)

Description copied from interface: ATManager

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

Specified by:

scanProcedures in interface ATManager<I,O>

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.
