Method Detail

parse

public static SignatureNode parse(InputStream in)
                           throws IOException,
                                  ParserSyntaxException

Throws:

IOException

ParserSyntaxException

yyerror

public void yyerror(String message)
             throws ParserSyntaxException

simplified error message.

Throws:

ParserSyntaxException

See Also:

#yyerror(java.lang.String, java.lang.String[])

yyerror

public void yyerror(String message,
           String[] expected,
           String found)
             throws ParserSyntaxException

(syntax) error message. Can be overwritten to control message format.

Parameters:

message - text to be displayed.

expected - list of acceptable tokens, if available.

Throws:

ParserSyntaxException

yyExpecting

protected String[] yyExpecting(int state)

computes list of expected tokens on error by tracing the tables.

Parameters:

state - for which to compute the list.

Returns:

list of token names.

yyparse

public Object yyparse(JavaSignatureLexer yyLex,
             Object ayydebug)
               throws IOException,
                      ParserSyntaxException

the generated parser, with debugging messages. Maintains a dynamic state and value stack.

Parameters:

yyLex - scanner.

yydebug - debug message writer implementing yyDebug, or null.

Returns:

result of the last reduction, if any.

Throws:

ParserSyntaxException - on irrecoverable parse error.

IOException

yyDefault

protected Object yyDefault(Object first)

executed at the beginning of a reduce action. Used as $$ = yyDefault($1), prior to the user-specified action, if any. Can be overwritten to provide deep copy, etc.

Parameters:

first - value for $1, or null.

Returns:

first.

yyparse

public Object yyparse(JavaSignatureLexer yyLex)
               throws IOException,
                      ParserSyntaxException

the generated parser. Maintains a dynamic state and value stack.

Parameters:

yyLex - scanner.

Returns:

result of the last reduction, if any.

Throws:

ParserSyntaxException - on irrecoverable parse error.

IOException
