Uses of NFAContext in org.antlr.analysis

Fields in org.antlr.analysis declared as NFAContext

Modifier and Type	Field and Description
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

Methods in org.antlr.analysis with parameters of type NFAContext

Modifier and Type	Method and Description
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.
