Function documentation

void AddError(TString& function, TString& errorMsg)

 Adds one error message. The function name and a message should be
 specified. The default length of the function name at the printout
 functions GetError() and PrintErrors(), is 24 characters.
 Independent of a previous call of SetErrorType() this function will
 always store the error message and will never throw an
 TFException - ecxeption.

void SetError(const char * function, const char * errorMsg, ...)

 Set one error message. The function name and a message should be
 specified. The default length of the function name at the printout
 functions GetError() and PrintErrors(), is 24 characters.
 The maximum length of the errorMsg is 1999 characters.
 Depending on a previous call of SetErrorType() this function will store
 the error message, will throw an TFException - ecxeption or will do both.

void RemveLastError()

 Removes the last, the youngest, error message from the list of messages

void SetMaxErrors(Int_t num)

 Set the maximum number of stored error messages. The default value is 20
 The function will remove the oldest error messages if the number is set
 to be less than the actual stored error messages.

void PrintErrors()

 Prints all error messages on standard output
 The oldest error is printed first

char * GetError(int num, char* errStr)

 Gets one error message as string. The function and the error message
 is copied into the string errStr and the pointer errStr is returned.
 num defines the 0 based index of the message. The errStr will be empty
 if num >=  NumErrors(). The oldes error has num == 0.
 errStr has to be long enough to hold the function name and the error
 message. 2100 bytes should always be enough

void SetErrorType(TFErrorType eType = kAllErr)

{fErrorType = eType;}
