An object of this class is used by other code that detects errors, so the error detection code can be separate from the error handling code. This class implements error handling by writing error messages to standard error output and maintaining a count of the number of errors.

| MapperErrorHandler::MapperErrorHandler (const char * name) |
The only constructur for a MapperErrorHandler.
assert( this->my_name == name ); assert( this->errors == 0 );
Definition at line 46 of file MapperErrorHandler.cpp.
MapperErrorHandler::~MapperErrorHandler (void) [virtual]
|
Definition at line 62 of file MapperErrorHandler.cpp.
void MapperErrorHandler::fatalError (const SAXParseException & exception) [virtual]
|
Handle a fatal XML parsing error.
This member function handles the situation by issuing an error report using the report member function, and incrementing the errors count.
Definition at line 133 of file MapperErrorHandler.cpp.
void MapperErrorHandler::error (const SAXParseException & exception) [virtual]
|
Handle an XML parsing error.
This member function handles the situation by issuing an error report using the report member function, and incrementing the errors count.
Definition at line 123 of file MapperErrorHandler.cpp.
void MapperErrorHandler::warning (const SAXParseException & exception) [virtual]
|
Handle an XML parsing situation which is worrying but not erroneous.
This member function handles the situation by issuing a warning using the report member function.
Definition at line 114 of file MapperErrorHandler.cpp.
void MapperErrorHandler::resetErrors (void) [virtual]
|
Clear the error handling state.
assert( this->errors == 0 );
Definition at line 143 of file MapperErrorHandler.cpp.
| void MapperErrorHandler::error (const error::element_error & e) |
Handle an error in a DOM element.
This member function handles the error by writing the message describing the error to cerr (standard error output), and showing the location of the element by showing the element tag and the element tags of all the elements enclosing that element.
This is the lowest-level error handling function for a DOM element error. Consider using one of the more specialised member functions, if possible.
| e | a description of the error |
Definition at line 177 of file MapperErrorHandler.cpp.
| void MapperErrorHandler::fatalError (const DOM_DOMException & exception) |
Handle a fatal DOM error.
This member function handles the error by writing a message describing the error to cerr (standard error output).
Definition at line 150 of file MapperErrorHandler.cpp.
| void MapperErrorHandler::fatalError (const XMLException & exception) |
Handle a fatal XML error.
This member function handles the situation by issuing an error report using the report member function, and incrementing the errors count.
Definition at line 161 of file MapperErrorHandler.cpp.
| void MapperErrorHandler::unexpectedError (void) |
Handle an unexpected error.
This member function hanles the error by writing a report to cerr (standard error output) and incrementing the errors count.
Definition at line 188 of file MapperErrorHandler.cpp.
| void MapperErrorHandler::badOptionArgument (const char option, const char * optarg) |
Handle a bad command-line option argument.
This member function handles the error by writing a report to cerr (standard error output) and incrementing the errors count.
| option | the command optoin |
| optarg | the erroneous option argument |
Definition at line 214 of file MapperErrorHandler.cpp.
| void MapperErrorHandler::error (const char * message) |
Handle a generic error.
This member function handles the error by writing a report to cerr (standard error output) and incrementing the errors count.
| description | a description of the error |
Definition at line 195 of file MapperErrorHandler.cpp.
| void MapperErrorHandler::warning (const char * message) |
Report a non serious problem.
The report is written to cerr (standard error output).
| description | a description of the error |
Definition at line 205 of file MapperErrorHandler.cpp.
| void MapperErrorHandler::report (const string entity, const unsigned line, const unsigned column, const string & severity, const string & message) const |
Output a formatted message.
| entity | the name of the entity (file or URL) to which this message pertains |
| line |
the line number of the entity to which this message pertains, or (unsigned)(-1) if the line numerb is unknown |
| column |
the column number of the entity to which this message pertains, or (unsigned)(-1) if the line numerb is unknown |
| severity | a description of the severity of the situation being reported |
| message | the situation being reported |
Definition at line 69 of file MapperErrorHandler.cpp.
| void MapperErrorHandler::report (const SAXParseException & ex, const string & severity) const |
Output a formatted message describing a parsing exception.
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
This member function uses information provided by the exception object to report an appropriate message.
| ex | the exception |
| severity | the severity of the exception |
Definition at line 91 of file MapperErrorHandler.cpp.
| void MapperErrorHandler::report (const DOM_DOMException & ex, const string & severity) const |
Output a formatted message describing a DOM exception.
| ex | the exception |
| severity | the severity of the exception |
| unsigned MapperErrorHandler::errors |
A count of the number of errors encountered so far.
Definition at line 78 of file MapperErrorHandler.h.
| const char* MapperErrorHandler::my_name |
The name of the program.
Used in some error messages.
Definition at line 84 of file MapperErrorHandler.h.
