$yyExpectedTokens
$yyFallback		%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.
$yyReduceMap		If a rule is not set, it has no handler.
$yyRuleInfo		array( array( int $lhs; Symbol on the left-hand side of the rule int $nrhs; Number of right-hand side symbols in the rule ),... );

Méthode	Description
Error ( $text )
PrintTrace ( )	Output debug information to output (php://output stream)
Trace ( $TraceFILE, $zTracePrompt )	Turn parser tracing on by giving a stream to which to write the trace and a prompt to preface each trace message. Tracing is turned off by making either argument NULL

Output debug information to output (php://output stream)

static public PrintTrace ( )

Trace() static public méthode

Inputs: - A stream resource to which trace output should be written. If NULL, then tracing is turned off. - A prefix string written at the beginning of every line of trace output. If NULL, then tracing is turned off. Outputs: - None.

static public Trace ( $TraceFILE, $zTracePrompt )

__destruct() public méthode

Deallocate and destroy a parser. Destructors are all called for all stack elements before shutting the parser down.

yy_reduce() public méthode

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)

public yy_reduce ( $yyruleno )

Perform a shift action.

public yy_shift ( $yyNewState, $yyMajor, $yypMinor )
