org.antlr.analysis.NFAContext

使用NFAContext的程序包

程序包	说明
org.antlr.analysis

org.antlr.analysis中NFAContext的使用

声明为NFAContext的org.antlr.analysis中的字段

修饰符和类型	字段	说明
NFAContext	NFAConfiguration.context	What is the stack of rule invocations that got us to state?
protected NFAContext[]	NFAToDFAConverter.contextTrees	While converting NFA, we must track states that reference other rule's NFAs so we know what to do at the end of a rule.
NFAContext	NFAContext.parent

参数类型为NFAContext的org.antlr.analysis中的方法

修饰符和类型	方法	说明
NFAConfiguration	DFAState.addNFAConfiguration(NFAState state, int alt, NFAContext context, SemanticContext semanticContext)
void	NFAToDFAConverter.closure(NFAState p, int alt, NFAContext context, SemanticContext semanticContext, DFAState d, boolean collectPredicates)	Where can we get from NFA state p traversing only epsilon transitions? Add new NFA states + context to DFA state d.
boolean	NFAContext.conflictsWith(NFAContext other)	Two contexts conflict() if they are equals() or one is a stack suffix of the other.
protected boolean	NFAContext.suffix(NFAContext other)	[$] suffix any context [21 $] suffix [21 12 $] [21 12 $] suffix [21 $] [21 18 $] suffix [21 18 12 9 $] [21 18 12 9 $] suffix [21 18 $] [21 12 $] not suffix [21 9 $] Example "[21 $] suffix [21 12 $]" means: rule r invoked current rule from state 21.

参数类型为NFAContext的org.antlr.analysis中的构造器

构造器	说明
NFAConfiguration(int state, int alt, NFAContext context, SemanticContext semanticContext)
NFAContext(NFAContext parent, NFAState invokingState)
