Function Documentation

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.

void Break ( const char *  location,
const char *  va_fmt,
  ...

void DefaultErrorHandler ( Int_t  level,
Bool_t  abort_bool,
const char *  location,
const char *  msg 
)

The default error handler function.

It prints the message on stderr and if abort is set it aborts the application.

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. By default DefaultErrorHandler() is used.
