Function Documentation

◆ AbstractMethod()

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.

Definition at line 260 of file TError.cxx.

◆ Break()

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

Use this function in case an error occurred.

Definition at line 310 of file TError.cxx.

◆ DebugPrint()

static void DebugPrint	(	const char *	fmt,
			...
	)

static

Print debugging message to stderr and, on Windows, to the system debugger.

Definition at line 64 of file TError.cxx.

◆ DefaultErrorHandler()

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.

Definition at line 125 of file TError.cxx.

◆ Error()

void Error	(	const char *	location,
		const char *	va_fmt,
			...
	)

Use this function in case an error occurred.

Definition at line 288 of file TError.cxx.

◆ ErrorHandler()

void ErrorHandler	(	Int_t	level,
		const char *	location,
		const char *	fmt,
		va_list	ap
	)

General error handler function. It calls the user set error handler.

Definition at line 202 of file TError.cxx.

◆ Fatal()

void Fatal	(	const char *	location,
		const char *	va_fmt,
			...
	)

Use this function in case of a fatal error. It will abort the program.

Definition at line 346 of file TError.cxx.

◆ GetErrorHandler()

ErrorHandlerFunc_t GetErrorHandler ( )

Returns the current error handler function.

Definition at line 116 of file TError.cxx.

◆ Info()

void Info	(	const char *	location,
		const char *	va_fmt,
			...
	)

Use this function for informational messages.

Definition at line 321 of file TError.cxx.

◆ MayNotUse()

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.

Definition at line 269 of file TError.cxx.

◆ Obsolete()

void Obsolete	(	const char *	function,
		const char *	asOfVers,
		const char *	removedFromVers
	)

Use this function to declare a function obsolete.

Specify as of which version the method is obsolete and as from which version it will be removed.

Definition at line 278 of file TError.cxx.

◆ SetErrorHandler()

ErrorHandlerFunc_t SetErrorHandler ( ErrorHandlerFunc_t newhandler )

Set an errorhandler function. Returns the old handler.

Definition at line 106 of file TError.cxx.

◆ SysError()

void SysError	(	const char *	location,
		const char *	va_fmt,
			...
	)

Use this function in case a system (OS or GUI) related error occurred.

Definition at line 299 of file TError.cxx.

◆ Warning()

void Warning	(	const char *	location,
		const char *	va_fmt,
			...
	)

Use this function in warning situations.

Definition at line 332 of file TError.cxx.

Variable Documentation

◆ gErrorAbortLevel

Int_t gErrorAbortLevel = kSysError+1

Definition at line 44 of file TError.cxx.

◆ gErrorHandler

ErrorHandlerFunc_t gErrorHandler = DefaultErrorHandler

static

Definition at line 58 of file TError.cxx.

◆ gErrorIgnoreLevel

Int_t gErrorIgnoreLevel = kUnset

Definition at line 43 of file TError.cxx.

◆ gErrorMutex

TVirtualMutex* gErrorMutex = 0

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.

Definition at line 41 of file TError.cxx.

◆ gPrintViaErrorHandler

Bool_t gPrintViaErrorHandler = kFALSE

Definition at line 45 of file TError.cxx.

◆ kAssertMsg

const char* kAssertMsg = "%s violated at line %d of `%s'"

Definition at line 47 of file TError.cxx.

◆ kCheckMsg

const char* kCheckMsg = "%s not true at line %d of `%s'"

Definition at line 48 of file TError.cxx.
