Examples of ParserRuleContext

org.antlr.v4.runtime.ParserRuleContext
A rule invocation record for parsing. Contains all of the information about the current rule not stored in the RuleContext. It handles parse tree children list, Any ATN state tracing, and the default values available for rule indications: start, stop, rule index, current alt number, current ATN state. Subclasses made for each rule and grammar track the parameters, return values, locals, and labels specific to that rule. These are the objects that are returned from rules. Note text is not an actual field of a rule return value; it is computed from start and stop using the input stream's toString() method. I could add a ctor to this so that we can pass in and store the input stream, but I'm not sure we want to do that. It would seem to be undefined to get the .text property anyway if the rule matches tokens from multiple input streams. I do not use getters for fields of objects that are used simply to group values such as this aggregate. The getters/setters are there to satisfy the superclass interface.
