Property	Type	Description
$YY2TBLSTATE
$YYNLSTATES
$action		Table of actions. Indexed according to $actionBase comment.
$actionBase		Map of states to a displacement into the $action table. The corresponding action for this state/symbol pair is $action[$actionBase[$state] + $symbol]. If $actionBase[$state] is 0, the action is defaulted, i.e. $actionDefault[$state] should be used instead.
$actionCheck		Table indexed analogously to $action. If $actionCheck[$actionBase[$state] + $symbol] != $symbol then the action is defaulted, i.e. $actionDefault[$state] should be used instead.
$actionDefault		Map of states to their default action
$actionTableSize		Size of $action table
$defaultAction		Action number signifying default action
$endAttributeStack		End attribute stack
$endAttributes		End attributes of last *shifted* token
$errorHandler		Error handler
$errorState		Error state, used to avoid error floods
$errorSymbol		Symbol number of error recovery token
$errors		Errors collected during last parse
$goto		Table of states to goto after reduction. Indexed according to $gotoBase comment.
$gotoBase		Map of non-terminals to a displacement into the $goto table. The corresponding goto state for this non-terminal/state pair is $goto[$gotoBase[$nonTerminal] + $state] (unless defaulted)
$gotoCheck		Table indexed analogously to $goto. If $gotoCheck[$gotoBase[$nonTerminal] + $state] != $nonTerminal then the goto state is defaulted, i.e. $gotoDefault[$nonTerminal] should be used.
$gotoDefault		Map of non-terminals to the default state to goto after their reduction
$gotoTableSize		Size of $goto table
$invalidSymbol		Symbol number signifying an invalid token
$lexer		Lexer that is used when parsing
$lookaheadStartAttributes		Start attributes of last *read* token
$productions		Names of the production rules (only necessary for debugging)
$ruleToLength		Map of rules to the length of their right-hand side, which is the number of elements that have to be popped from the stack(s) on reduction.
$ruleToNonTerminal		Map of rules to the non-terminal on their left-hand side, i.e. the non-terminal to use for determining the state to goto after reduction.
$semStack		Semantic value stack (contains values of tokens and semantic action results)
$semValue		Temporary value containing the result of last semantic action (reduction)
$specialNames
$stackPos		Position in stacks (state stack, semantic value stack, attribute stack)
$startAttributeStack		Start attribute stack
$symbolToName		Map of symbols to their names
$tokenToSymbol		Map of lexer tokens to internal symbols
$tokenToSymbolMapSize		Size of $tokenToSymbol map
$unexpectedTokenRule		Rule number signifying that an unexpected token was encountered
