public JavaParser()

Method Detail

yyerror

public void yyerror(java.lang.String message)

simplified error message.

See Also:

yyerror

yyerror

public void yyerror(java.lang.String message,
                    java.lang.String[] expected)

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

Parameters:

message - text to be displayed.

expected - vector of acceptable tokens, if available.

yyExpecting

protected java.lang.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 java.lang.Object yyparse(JavaParser.yyInput yyLex,
                                java.lang.Object yydebug)
                         throws java.io.IOException,
                                JavaParser.yyException

the generated parser, with debugging messages. Maintains a state and a value stack, currently with fixed maximum size.

Parameters:

yyLex - scanner.

yydebug - debug message writer implementing yyDebug, or null.

Returns:

result of the last reduction, if any.

Throws:

JavaParser.yyException - on irrecoverable parse error.

java.io.IOException

JavaParser.yyException

yyDefault

protected java.lang.Object yyDefault(java.lang.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 java.lang.Object yyparse(JavaParser.yyInput yyLex)
                         throws java.io.IOException,
                                JavaParser.yyException

the generated parser. Maintains a state and a value stack, currently with fixed maximum size.

Parameters:

yyLex - scanner.

Returns:

result of the last reduction, if any.

Throws:

JavaParser.yyException - on irrecoverable parse error.

java.io.IOException

JavaParser.yyException
