Method Detail

production_table

public short[][] production_table()

Access to production table.

Specified by:

production_table in class java_cup.runtime.lr_parser

action_table

public short[][] action_table()

Access to parse-action table.

Specified by:

action_table in class java_cup.runtime.lr_parser

reduce_table

public short[][] reduce_table()

Access to reduce_goto table.

Specified by:

reduce_table in class java_cup.runtime.lr_parser

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,
                                Stack stack,
                                int top)
                                  throws Exception

Invoke a user supplied parse action.

Specified by:

do_action in class java_cup.runtime.lr_parser

Throws:

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:

error_sym in class java_cup.runtime.lr_parser

scan

public java_cup.runtime.Symbol scan()
                             throws Exception

Scan to get the next Symbol.

Overrides:

scan in class java_cup.runtime.lr_parser

Throws:

Exception

setFile

public void setFile(String file)

report_error

public void report_error(String message,
                Object info)

Called by the parser when it detects a syntax error. This is overridden so that it does nothing. Instead the parser relies upon explicit calls to routine error(String) or error(String, int line, int column) which store details of synatx errors into an error buffer for retrieval after the parse call completes.

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.

unrecovered_syntax_error

public void unrecovered_syntax_error(java_cup.runtime.Symbol cur_token)

Called by the parser when it is unable to recover from one or more syntax errors

Overrides:

unrecovered_syntax_error in class java_cup.runtime.lr_parser

Parameters:

cur_token - the token current at the point in the token stream where the recovery process fails

error

public void error(String message)

error

public void error(String message,
         int line,
         int col)

getFile

public String getFile()

getErrorCount

public int getErrorCount()

getErrors

public String getErrors()

debug_reduce

public void debug_reduce(int prod_num,
                int nt_num,
                int rhs_size)

Do debug output for a reduce.

Overrides:

debug_reduce in class java_cup.runtime.lr_parser

Parameters:

prod_num - the production we are reducing with.

nt_num - the index of the LHS non terminal.

rhs_size - the size of the RHS.

debug_shift

public void debug_shift(java_cup.runtime.Symbol shift_tkn)

Do debug output for shift.

Overrides:

debug_shift in class java_cup.runtime.lr_parser

Parameters:

shift_tkn - the Symbol being shifted onto the stack.
