Class InterpreterRuleContext

java.lang.Object

org.antlr.v4.runtime.RuleContext

org.antlr.v4.runtime.ParserRuleContext

org.antlr.v4.runtime.InterpreterRuleContext

All Implemented Interfaces:

ParseTree, RuleNode, SyntaxTree, Tree

Direct Known Subclasses:

GrammarInterpreterRuleContext

public class InterpreterRuleContext
extends ParserRuleContext

This class extends ParserRuleContext by allowing the value of getRuleIndex() to be explicitly set for the context.

ParserRuleContext does not include field storage for the rule index since the context classes created by the code generator override the getRuleIndex() method to return the correct value for that context. Since the parser interpreter does not use the context classes generated for a parser, this class (with slightly more memory overhead per node) is used to provide equivalent functionality.
