report_error
Description copied from class:org.acplt.oncrpc.apps.jrpcgen.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 classorg.acplt.oncrpc.apps.jrpcgen.cup_runtime.lr_parser
- Parameters:
message
- an error message.info
- an extra object reserved for use by specialized subclasses.

syntax_error
public void syntax_error(org.acplt.oncrpc.apps.jrpcgen.cup_runtime.Symbol cur_token) Description copied from class:org.acplt.oncrpc.apps.jrpcgen.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 classorg.acplt.oncrpc.apps.jrpcgen.cup_runtime.lr_parser
- Parameters:
cur_token
- the current lookahead Symbol.
-
report_fatal_error
Description copied from class:org.acplt.oncrpc.apps.jrpcgen.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 classorg.acplt.oncrpc.apps.jrpcgen.cup_runtime.lr_parser
- Parameters:
message
- an error message.info
- an extra object reserved for use by specialized subclasses.
