Constructor Detail

StackSBA

public StackSBA(ProceduralInputAlphabet<I> alphabet,
                @Nullable I initialCall,
                Map<I,? extends DFA<? extends S,I>> procedures)

Method Detail

getTransition

public StackState<S,I,DFA<S,I>> getTransition(StackState<S,I,DFA<S,I>> state,
                                                                I input)

Description copied from interface: DeterministicTransitionSystem

Retrieves the transition triggered by the given input symbol.

Specified by:

getTransition in interface DeterministicTransitionSystem<StackState<S,I,DFA<S,I>>,I,StackState<S,I,DFA<S,I>>>

Parameters:

state - the source state.

input - the input symbol.

Returns:

the transition triggered by the given input symbol, or null if no transition is triggered.

See Also:

TransitionSystem.getTransitions(Object, Object)

isAccepting

public boolean isAccepting(StackState<S,I,DFA<S,I>> state)

Description copied from interface: AcceptorTS

Checks whether the given state is accepting.

Specified by:

isAccepting in interface AcceptorTS<S,I>

Parameters:

state - the state

Returns:

true if the state is accepting, false otherwise.

getInitialState

public StackState<S,I,DFA<S,I>> getInitialState()

Description copied from interface: SimpleDTS

Retrieves the initial state of this transition system.

Specified by:

getInitialState in interface SimpleDTS<S,I>

Returns:

the initial state.

See Also:

SimpleTS.getInitialStates()

getInitialProcedure

public @Nullable I getInitialProcedure()

getInputAlphabet

public ProceduralInputAlphabet<I> getInputAlphabet()

Specified by:

getInputAlphabet in interface InputAlphabetHolder<S>

getProcedures

public Map<I,DFA<?,I>> getProcedures()

getProceduralInputs

public default Collection<I> getProceduralInputs()

Convenience method for getProceduralInputs(Collection) which uses the input alphabet of this system as constraints.

Returns:

a collection of defined inputs for this system's procedures.

getProcedure

public default @Nullable M getProcedure(I callSymbol)

Convenience method for getProcedures() to quickly return the procedure of a given call symbol.

Parameters:

callSymbol - the call symbol

Returns:

the corresponding procedure. May be null if this system does not have a procedure for the given call symbol.

See Also:

getProcedures()

size

public default int size()

Returns the size of this system which is given by the sum of the sizes of all procedures. Note that this value does not necessarily correspond to the classical notion of SimpleAutomaton.size(), since semantically a ProceduralSystem may be infinite-sized SimpleTS.

Specified by:

size in interface FiniteRepresentation

Returns:

the size of this system

graphView

public default Graph<?,?> graphView()

Specified by:

graphView in interface GraphViewable
