$yyFallback = array(

[line 344]

The next table maps tokens into fallback tokens. If a construct like the following:

%fallback ID X Y Z.

appears in the grammer, then ID becomes a fallback token for X, Y, and Z. Whenever one of the tokens X, Y, or Z is input to the parser but it does not parse, the type of the token is changed to ID and the parse is retried before an error is thrown.

Find the appropriate action for a parser given the non-terminal look-ahead token $iLookAhead.

If the look-ahead token is self::YYNOCODE, then check to see if the action is independent of the look-ahead. If it is, return the action, otherwise return self::YY_NO_ACTION.

yy_is_expected_token [line 635]

bool yy_is_expected_token(
int

yy_reduce [line 1095]

void yy_reduce(
int
$yyruleno)

Perform a reduce action and the shift that must immediately follow the reduce.

For a rule such as:

 A ::= B blah C. { dosomething(); }

This function will first call the action, if any, ("dosomething();" in our example), and then it will pop three states from the stack, one for each entry on the right-hand side of the expression (B, blah, and C in our example rule), and then push the result of the action back on to the stack with the resulting state reduced to (as described in the .out file)

Parameters:

int $yyruleno — Number of the rule by which to reduce

[ Top ]

yy_shift [line 786]

void yy_shift(
int
$yyNewState, int

Perform a shift action.

Parameters:

int	`$yyNewState`	—	The new state to shift in
int	`$yyMajor`	—	The major token to shift in
mixed	`$yypMinor`	—	the minor token to shift in
