Method Detail

production_table

public short[][] production_table()

Access to production table.

Specified by:

production_table in class lr_parser

action_table

public short[][] action_table()

Access to parse-action table.

Specified by:

action_table in class lr_parser

See Also:

lr_parser.get_action(int, int)

reduce_table

public short[][] reduce_table()

Access to reduce_goto table.

Specified by:

reduce_table in class lr_parser

See Also:

init_actions

protected void init_actions()

Action encapsulation object initializer.

Specified by:

init_actions in class lr_parser

do_action

public Symbol do_action(int act_num,
                        lr_parser parser,
                        Stack stack,
                        int top)
                 throws Exception

Invoke a user supplied parse action.

Specified by:

do_action in class 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:

Exception

start_state

public int start_state()

Indicates start state.

Specified by:

start_state in class lr_parser

start_production

public int start_production()

Indicates start production.

Specified by:

start_production in class lr_parser

main

public static void main(String[] args)

report_error

public void report_error(String message,
                         Object info)

Description copied from class: 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 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)
                        throws XPathParseExceptionHuge

Description copied from class: 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 lr_parser

Parameters:

message - an error message.

info - an extra object reserved for use by specialized subclasses.

Throws:

XPathParseExceptionHuge

syntax_error

public void syntax_error(Symbol cur_token)

Description copied from class: 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 lr_parser

Parameters:

cur_token - the current lookahead Symbol.

unrecovered_syntax_error

public void unrecovered_syntax_error(Symbol cur_token)
                              throws XPathParseExceptionHuge

Description copied from class: lr_parser

This method is called if it is determined that syntax error recovery has been unsuccessful. Here in the base class we report a fatal error.

Overrides:

unrecovered_syntax_error in class lr_parser

Parameters:

cur_token - the current lookahead Symbol.

Throws:

XPathParseExceptionHuge
