$yyFallback = array(

[line 171]

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.

Method Detail

__destruct (Destructor) [line 311]

void __destruct(
)

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

[ Top ]

doParse [line 626]

void doParse(
int
$yymajor, mixed
$yytokenvalue, [mixed
$extraargument = null])

The main parser program.

The first argument is a pointer to a structure obtained from "ParseAlloc" which describes the current state of the parser. The second argument is the major token number. The third is the minor token. The fourth optional argument is whatever the user wants (and specified in the grammar) and is available for use by the action routines.

Inputs:

A pointer to the parser (an opaque structure.)
The major token number.
The minor token number (token value).
An option argument of a grammar-specified type.

Outputs: None.

Parameters:

int	`$yymajor`	—	the token number
mixed	`$yytokenvalue`	—	the token value
mixed	`$extraargument`	—	any extra arguments that should be passed to handlers

[ Top ]

ParseTokenName [line 244]

string ParseTokenName(
int
$tokenType)

This function returns the symbolic name associated with a token value.

Parameters:

int $tokenType —

[ Top ]

Trace [line 192]

void Trace(
resource
$TraceFILE, string
$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

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.

Parameters:

resource	`$TraceFILE`	—
string	`$zTracePrompt`	—

[ Top ]

yy_accept [line 589]

void yy_accept(
[
$extraargument = null])

Parameters:

$extraargument —

[ Top ]

yy_destructor [line 258]

void yy_destructor(

$yymajor, 
$yypminor)

Parameters:

	`$yymajor`	—
	`$yypminor`	—

[ Top ]

yy_find_reduce_action [line 371]

void yy_find_reduce_action(
int
$stateno, int
$iLookAhead)

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

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

Parameters:

int	`$stateno`	—	Current state number
int	`$iLookAhead`	—	The look-ahead token

[ Top ]

yy_find_shift_action [line 327]

void yy_find_shift_action(
int
$iLookAhead)

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

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

Parameters:

int $iLookAhead — The look-ahead token

[ Top ]

yy_parse_failed [line 558]

void yy_parse_failed(
[
$extraargument = null])

The following code executes when the parse fails

Parameters:

$extraargument —

[ Top ]

yy_pop_parser_stack [line 285]

int yy_pop_parser_stack(
ParseyyParser
0)

Pop the parser's stack once.

If there is a destructor routine associated with the token which is popped from the stack, then call it.

Return the major token number for the symbol popped.

Parameters:

ParseyyParser 0 —

[ Top ]

yy_r0 [line 465]

void yy_r0(
)

[ Top ]

yy_reduce [line 503]

void yy_reduce(
int
$yyruleno, [
$extraargument = null])

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	`$yyruleno`	—	Number of the rule by which to reduce
	`$extraargument`	—

[ Top ]

yy_shift [line 400]

void yy_shift(
int
$yyNewState, int
$yyMajor, mixed
$yypMinor, [
$extraargument = null])

Perform a shift action.

Parameters:

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

[ Top ]

yy_syntax_error [line 578]

void yy_syntax_error(
int
$yymajor, mixed
$yyminor, [
$extraargument = null])

The following code executes when a syntax error first occurs.

Parameters:

int	`$yymajor`	—	The major type of the error token
mixed	`$yyminor`	—	The minor type of the error token
	`$extraargument`	—
