TagParserData

Symbol number of error recovery token

Action number signifying default action

Rule number signifying that an unexpected token was encountered

Number of non-leaf states

Map of lexer tokens to internal symbols

Map of states to a displacement into the self::Action table. The corresponding action for this state/symbol pair is self::Action[self::ActionBase[$state] + $symbol]. If self::ActionBase[$state] is 0, the action is defaulted, i.e. self::ActionDefault[$state] should be used instead.

Table of actions. Indexed according to self::ActionBase comment.

Table indexed analogously to self::Action. If self::ActionCheck[self::ActionBase[$state] + $symbol] != $symbol then the action is defaulted, i.e. self::ActionDefault[$state] should be used instead.

Map of states to their default action

Map of non-terminals to a displacement into the self::Goto table. The corresponding goto state for this non-terminal/state pair is self::Goto[self::GotoBase[$nonTerminal] + $state] (unless defaulted)

Table of states to goto after reduction. Indexed according to self::GotoBase comment.

Table indexed analogously to self::Goto. If self::GotoCheck[self::GotoBase[$nonTerminal] + $state] != $nonTerminal then the goto state is defaulted, i.e. self::GotoDefault[$nonTerminal] should be used.

Map of non-terminals to the default state to goto after their reduction

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.

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.

Map of symbols to their names

Temporary value containing the result of last semantic action (reduction)

Semantic value stack (contains values of tokens and semantic action results)
