Constructor which sets the default scanner.
Method Detail

production_table

public short[][] production_table()
Access to production table.
Overrides:
production_table in class java_cup.runtime.lr_parser

action_table

public short[][] action_table()
Access to parse-action table.
Overrides:
action_table in class java_cup.runtime.lr_parser

reduce_table

public short[][] reduce_table()
Access to reduce_goto table.
Overrides:
reduce_table in class java_cup.runtime.lr_parser

init_actions

protected void init_actions()
Action encapsulation object initializer.
Overrides:
init_actions in class java_cup.runtime.lr_parser

do_action

public java_cup.runtime.Symbol do_action(int act_num,
                                         java_cup.runtime.lr_parser parser,
                                         Stack stack,
                                         int top)
                                  throws Exception
Invoke a user supplied parse action.
Overrides:
do_action in class java_cup.runtime.lr_parser

start_state

public int start_state()
Indicates start state.
Overrides:
start_state in class java_cup.runtime.lr_parser

start_production

public int start_production()
Indicates start production.
Overrides:
start_production in class java_cup.runtime.lr_parser

EOF_sym

public int EOF_sym()
EOF Symbol index.
Overrides:
EOF_sym in class java_cup.runtime.lr_parser

error_sym

public int error_sym()
error Symbol index.
Overrides:
error_sym in class java_cup.runtime.lr_parser

main

public static void main(String[] args)
                 throws Exception
This main is included to enable the parser to be run by typing an expression on the standard input stream.

report_fatal_error

public void report_fatal_error(String message,
                               Object info)
                        throws FailedParseException
Report a fatal error. This method takes a message string and an additional object (to be used by specializations implemented in subclasses). This method overrides the lr_parser implementation to throw the more specific FailedParseException.
Overrides:
report_fatal_error in class java_cup.runtime.lr_parser
Parameters:
String - message, an error message.
Object - info, an extra object reserved for use by specialized subclasses.

syntax_error

public void syntax_error(java_cup.runtime.Symbol curToken)
This method overrides lr_parser.syntax_error(Symbol) to keep the parser from outputting error messages to System.err. All messages will be passed using the FailedParseException.
Overrides:
syntax_error in class java_cup.runtime.lr_parser

unrecovered_syntax_error

public void unrecovered_syntax_error(java_cup.runtime.Symbol curToken)
                              throws FailedParseException
This method overrides lr_parser.unrecovered_syntax_error(Symbol). It calls report_fatal_error just as the parent method did, but adds the current token string to the message which will be put into a FailedParseException.
Overrides:
unrecovered_syntax_error in class java_cup.runtime.lr_parser
Parameters:
Symbol - curToken, the token the parser has failed on
