/* Next are that tables used to determine what action to take based on the
** current state and lookahead token. These tables are used to implement
** functions that take a state number and lookahead value and return an
** action integer.
**
** Suppose the action integer is N. Then the action is determined as
** follows
**
** 0 <= N < self::YYNSTATE Shift N. That is,
** push the lookahead
** token onto the stack
** and goto state N.
**
** self::YYNSTATE <= N < self::YYNSTATE+self::YYNRULE Reduce by rule N-YYNSTATE.
**
** N == self::YYNSTATE+self::YYNRULE A syntax error has occurred.
**
** N == self::YYNSTATE+self::YYNRULE+1 The parser accepts its
** input. (and concludes parsing)
**
** N == self::YYNSTATE+self::YYNRULE+2 No such action. Denotes unused
** slots in the yy_action[] table.
**
** The action table is constructed as a single large static array $yy_action.
** Given state S and lookahead X, the action is computed as
**
** self::$yy_action[self::$yy_shift_ofst[S] + X ]
**
** If the index value self::$yy_shift_ofst[S]+X is out of range or if the value
** self::$yy_lookahead[self::$yy_shift_ofst[S]+X] is not equal to X or if
** self::$yy_shift_ofst[S] is equal to self::YY_SHIFT_USE_DFLT, it means that
** the action is not in the table and that self::$yy_default[S] should be used instead.
**
** The formula above is for computing the action when the lookahead is
** a terminal symbol. If the lookahead is a non-terminal (as occurs after
** a reduce action) then the static $yy_reduce_ofst array is used in place of
** the static $yy_shift_ofst array and self::YY_REDUCE_USE_DFLT is used in place of
** self::YY_SHIFT_USE_DFLT.
**
** The following are the tables generated in this section:
**
** self::$yy_action A single table containing all actions.
** self::$yy_lookahead A table containing the lookahead for each entry in
** yy_action. Used to detect hash collisions.
** self::$yy_shift_ofst For each state, the offset into self::$yy_action for
** shifting terminals.
** self::$yy_reduce_ofst For each state, the offset into self::$yy_action for
** shifting non-terminals after a reduce.
** self::$yy_default Default action for each state.
