Parameters:
act_num - the internal index of the action to be performed.
parser - the parser object we are acting for.
stack - the parse stack of that object.
top - the index of the top element of the parse stack.
Throws:
Exception

public int start_state()
start state

Specified by:
start_state in class java_cup.runtime.lr_parser

start_production

public int start_production()
start production

Specified by:
start_production in class java_cup.runtime.lr_parser

user_init

public void user_init()
               throws Exception
user initialization

Overrides:

report_error

public void report_error(String message,
                         Object info)
Description copied from class: java_cup.runtime.lr_parser
Report a non fatal error (or warning). This method takes a message string and an additional object (to be used by specializations implemented in subclasses). Here in the base class a very simple implementation is provided which simply prints the message to System.err.

Overrides:
report_error in class java_cup.runtime.lr_parser
Parameters:
message - an error message.
info - an extra object reserved for use by specialized subclasses.

report_fatal_error

public void report_fatal_error(String message,
                               Object info)
Description copied from class: java_cup.runtime.lr_parser
Report a fatal error. This method takes a message string and an additional object (to be used by specializations implemented in subclasses). Here in the base class a very simple implementation is provided which reports the error then throws an exception.

Overrides:
report_fatal_error in class java_cup.runtime.lr_parser
Parameters:
message - an error message.
info - an extra object reserved for use by specialized subclasses.
