public Class RuleClosureTransition

Class Inheritance

java.lang.Object
org.antlr.analysis.Transition
org.antlr.analysis.RuleClosureTransition

Imports

org.antlr.tool.Rule

A transition used to reference another rule. It tracks two targets really: the actual transition target and the state following the state that refers to the other rule. Conversion of an NFA that falls off the end of a rule will be able to figure out who invoked that rule because of these special transitions.
