Uses of Label in org.antlr.analysis
Subclasses of Label in org.antlr.analysisFields in org.antlr.analysis declared as LabelModifier and TypeFieldDescriptionNFAState.incidentEdgeLabel
For o-A->o type NFA tranitions, record the label that leads to this state.Transition.label
What label must be consumed to transition to targetFields in org.antlr.analysis with type parameters of type LabelModifier and TypeFieldDescriptionprotected OrderedHashSet<Label>
DFAState.reachableLabels
As this state is constructed (i.e., as NFA states are added), we can easily check for non-epsilon transitions because the only transition that could be a valid label is transition(0).Methods in org.antlr.analysis that return LabelMethods in org.antlr.analysis that return types with arguments of type LabelModifier and TypeMethodDescriptionDFAState.getReachableLabels()
DecisionProbe.getSampleNonDeterministicInputSequence
(DFAState targetState) Return a List<Label> indicating an input sequence that can be matched from the start state of the DFA to the targetState (which is known to have a problem).Methods in org.antlr.analysis with parameters of type LabelModifier and TypeMethodDescriptionvoid
protected void
DFAState.addReachableLabel
(Label label) Add label uniquely and disjointly; intersection with another set or int/char forces breaking up the set(s).int
DFAState.addTransition
(DFAState target, Label label) Add a transition from this state to target with label.protected static int
NFAToDFAConverter.addTransition
(DFAState d, Label label, DFAState targetState, Map<Integer, Transition> targetToLabelMap) Add a transition from state d to targetState with label in normal case.int
static boolean
boolean
Given the set of NFA states in DFA state d, find all NFA states reachable traversing label arcs.Method parameters in org.antlr.analysis with type arguments of type LabelModifier and TypeMethodDescriptionDecisionProbe.getInputSequenceDisplay
(List<? extends Label> labels) Given List<Label>, return a String with a useful representation of the associated input string.protected boolean
DecisionProbe.getNFAPath
(NFAState s, int labelIndex, List<? extends Label> labels, List<? super NFAState> path) Given a sample input sequence, you usually would like to know the path taken through the NFA.DecisionProbe.getNFAPathStatesForAlt
(int firstAlt, int alt, List<? extends Label> labels) Given an alternative associated with a nondeterministic DFA state, find the path of NFA states associated with the labels sequence.protected void
DecisionProbe.getSampleInputSequenceUsingStateSet
(State startState, State targetState, Set<DFAState> states, List<Label> labels) Given a start state and a final state, find a list of edge labels between the two ignoring epsilon.Constructors in org.antlr.analysis with parameters of type Label -
