**

** self::$yy_action[self::$yy_shift_ofst[S] + X ]

|
** 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.

**
|

** 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.
