reduce_table

public short[][] reduce_table()
Access to reduce_goto table.

Specified by:
reduce_table in class java_cup.runtime.lr_parser
See Also:

init_actions

protected void init_actions()
Action encapsulation object initializer.

Specified by:
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,
                                         java.util.Stack stack,
                                         int top)
                                  throws java.lang.Exception
Invoke a user supplied parse action.

Specified by:
do_action in class java_cup.runtime.lr_parser
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:
java.lang.Exception

start_state

public int start_state()
Indicates start state.

Specified by:
start_state in class java_cup.runtime.lr_parser

start_production

public int start_production()
Indicates start production.

Specified by:
start_production in class java_cup.runtime.lr_parser

EOF_sym

public int EOF_sym()
EOF Symbol index.

Specified by:
EOF_sym in class java_cup.runtime.lr_parser

error_sym

public int error_sym()
error Symbol index.

Specified by:

scan

public java_cup.runtime.Symbol scan()
                             throws java.lang.Exception
Scan to get the next Symbol.

Overrides:
scan in class java_cup.runtime.lr_parser
Throws:
java.lang.Exception

getFilename

public static java.lang.String getFilename()

syntax_error

public void syntax_error(java_cup.runtime.Symbol cur_token)
Description copied from class: java_cup.runtime.lr_parser
This method is called when a syntax error has been detected and recovery is about to be invoked. Here in the base class we just emit a "Syntax error" error message.

Overrides:
syntax_error in class java_cup.runtime.lr_parser
Parameters:
cur_token - the current lookahead Symbol.

report_fatal_error

public void report_fatal_error(java.lang.String message,
                               java.lang.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.

getProgramNode

public static java.lang.Object getProgramNode()

setProgramNode

public static void setProgramNode(java.lang.Object n)
