Uses of Label in org.antlr.analysis
Subclasses of Label in org.antlr.analysis Modifier and Type Class Description class
ActionLabel
class
PredicateLabel
Fields in org.antlr.analysis declared as Label Modifier and Type Field Description Label
NFAState. incidentEdgeLabel
For o-A->o type NFA tranitions, record the label that leads to this state.Label
Transition. label
What label must be consumed to transition to targetFields in org.antlr.analysis with type parameters of type Label Modifier and Type Field Description protected 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 Label Modifier and Type Method Description protected Label
LL1DFA. getLabelForSet(IntervalSet edgeSet)
Methods in org.antlr.analysis that return types with arguments of type Label Modifier and Type Method Description OrderedHashSet<Label>
DFAState. getReachableLabels()
java.util.List<Label>
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 Label Modifier and Type Method Description void
Label. add(Label a)
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, java.util.Map<java.lang.Integer,Transition> targetToLabelMap)
Add a transition from state d to targetState with label in normal case.int
Label. compareTo(Label o)
static boolean
Label. intersect(Label label, Label edgeLabel)
boolean
Label. matches(Label other)
DFAState
NFAToDFAConverter. reach(DFAState d, Label label)
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 Label Modifier and Type Method Description java.lang.String
DecisionProbe. getInputSequenceDisplay(java.util.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, java.util.List<? extends Label> labels, java.util.List<? super NFAState> path)
Given a sample input sequence, you usually would like to know the path taken through the NFA.java.util.List<? extends NFAState>
DecisionProbe. getNFAPathStatesForAlt(int firstAlt, int alt, java.util.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, java.util.Set<DFAState> states, java.util.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 Constructor Description Transition(Label label, State target)
