org.antlr.analysis中Label的使用

org.antlr.analysis中Label的子类

修饰符和类型	类	说明
class	ActionLabel
class	PredicateLabel

声明为Label的org.antlr.analysis中的字段

修饰符和类型	字段	说明
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 target

类型参数类型为Label的org.antlr.analysis中的字段

修饰符和类型	字段	说明
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).

返回Label的org.antlr.analysis中的方法

修饰符和类型	方法	说明
protected Label	LL1DFA.getLabelForSet(IntervalSet edgeSet)

返回变量类型为Label的类型的org.antlr.analysis中的方法

修饰符和类型	方法	说明
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).

参数类型为Label的org.antlr.analysis中的方法

修饰符和类型	方法	说明
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.

类型变量类型为Label的org.antlr.analysis中的方法参数

修饰符和类型	方法	说明
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.

参数类型为Label的org.antlr.analysis中的构造器

构造器	说明
Transition(Label label, State target)

org.antlr.tool中Label的使用

参数类型为Label的org.antlr.tool中的方法

修饰符和类型	方法	说明
protected static java.lang.Integer	RandomPhrase.getTokenType(Label label)
