InterpreterRuleContext

This class extends {@link ParserRuleContext} by allowing the value of {@link #getRuleIndex} to be explicitly set for the context.

<p> {@link ParserRuleContext} does not include field storage for the rule index since the context classes created by the code generator override the {@link #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.</p>

From ParserRuleContext

EMPTY ParserRuleContext EMPTY;: @uml @__gshared
children ParseTree[] children;: If we are debugging or building a parse tree for a visitor, we need to track all of the tokens and rule invocations associated with this rule's context. This is empty for parsing w/o tree constr. operation because we don't the need to track the details about how we parse this rule.
start Token start;: Undocumented in source.
stop Token stop;: Undocumented in source.
exception RecognitionException exception;: The exception that forced this rule to return. If the rule successfully completed, this is {@code null}.
copyFrom void copyFrom(ParserRuleContext ctx): COPY a ctx (I'm deliberately not using copy constructor) to avoid confusion with creating node with parent. Does not copy children (except error leaves).
enterRule void enterRule(ParseTreeListener listener): Undocumented in source. Be warned that the author may not have intended to support it.
exitRule void exitRule(ParseTreeListener listener): Undocumented in source. Be warned that the author may not have intended to support it.
addAnyChild ParseTree addAnyChild(ParseTree t): Add a parse tree node to this as a child. Works for internal and leaf nodes. Does not set parent link; other add methods must do that. Other addChild methods call this.
addChild RuleContext addChild(RuleContext ruleInvocation): Undocumented in source. Be warned that the author may not have intended to support it.
addChild TerminalNode addChild(TerminalNode t): Add a token leaf node child and force its parent to be this node.
removeLastChild void removeLastChild(): Used by enterOuterAlt to toss out a RuleContext previously added as we entered a rule. If we have # label, we will need to remove generic ruleContext object.
addChild TerminalNode addChild(Token matchedToken): Undocumented in source. Be warned that the author may not have intended to support it.
addErrorNode ErrorNode addErrorNode(Token badToken): Undocumented in source. Be warned that the author may not have intended to support it.
getParent ParserRuleContext getParent(): Override to make type more specific @uml @override
getChild ParseTree getChild(int i): @uml @override
getChild auto getChild(int i): Undocumented in source. Be warned that the author may not have intended to support it.
getToken TerminalNode getToken(int ttype, int i): Undocumented in source. Be warned that the author may not have intended to support it.
getTokens TerminalNode[] getTokens(int ttype): Undocumented in source. Be warned that the author may not have intended to support it.
getRuleContext T getRuleContext(int i): Undocumented in source. Be warned that the author may not have intended to support it.
getRuleContexts T[] getRuleContexts(): Undocumented in source. Be warned that the author may not have intended to support it.
getChildCount int getChildCount(): @uml @override
getSourceInterval Interval getSourceInterval(): @uml @override
getStart Token getStart(): Get the initial token in this context. Note that the range from start to stop is inclusive, so for rules that do not consume anything (for example, zero length or error productions) this token may exceed stop.
getStop Token getStop(): Get the final token in this context. Note that the range from start to stop is inclusive, so for rules that do not consume anything (for example, zero length or error productions) this token may precede start.
toInfoString string toInfoString(InterfaceParser recognizer): Used for rule context info debugging during parse-time, not so much for ATN debugging
