Functions | |
void | AbstractMethod (const char *method) |
This function can be used in abstract base classes in case one does not want to make the class a "real" (in C++ sense) ABC. | |
void | Break (const char *location, const char *fmt,...) |
Use this function in case an error occurred. | |
void | Error (const char *location, const char *fmt,...) |
Use this function in case an error occurred. | |
void | ErrorHandler (Int_t level, const char *location, const char *fmt, std::va_list ap) |
General error handler function. It calls the user set error handler. | |
void | Fatal (const char *location, const char *fmt,...) |
Use this function in case of a fatal error. It will abort the program. | |
ErrorHandlerFunc_t | GetErrorHandler () |
Returns the current error handler function. | |
ErrorSystemMsgHandlerFunc_t | ROOT::Internal::GetErrorSystemMsgHandler () |
static ROOT::Internal::ErrorSystemMsgHandlerFunc_t & | GetErrorSystemMsgHandlerRef () |
void | Info (const char *location, const char *fmt,...) |
Use this function for informational messages. | |
void | MayNotUse (const char *method) |
This function can be used in classes that should override a certain function, but in the inherited class the function makes no sense. | |
void | ROOT::Internal::MinimalErrorHandler (Int_t level, Bool_t abort_bool, const char *location, const char *msg) |
A very simple error handler that is usually replaced by the TROOT default error handler. | |
void | Obsolete (const char *function, const char *asOfVers, const char *removedFromVers) |
Use this function to declare a function obsolete. | |
ErrorHandlerFunc_t | SetErrorHandler (ErrorHandlerFunc_t newhandler) |
Set an errorhandler function. Returns the old handler. | |
ErrorSystemMsgHandlerFunc_t | ROOT::Internal::SetErrorSystemMsgHandler (ErrorSystemMsgHandlerFunc_t h) |
Returns the previous system error message handler. | |
void | SysError (const char *location, const char *fmt,...) |
Use this function in case a system (OS or GUI) related error occurred. | |
void | Warning (const char *location, const char *fmt,...) |
Use this function in warning situations. | |

void AbstractMethod | ( | const char * | method | ) |
This function can be used in abstract base classes in case one does not want to make the class a "real" (in C++ sense) ABC.
If this function is called it will warn the user that the function should have been overridden.

Error handling routines.
This file defines a number of global error handling routines: Warning(), Error(), SysError() and Fatal(). They all take a location string (where the error happened) and a printf style format string plus vararg's. In the end these functions call an errorhandler function. Initially the MinimalErrorHandler, which is supposed to be replaced by the proper DefaultErrorHandler()
