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 - Menge 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.
