Function Documentation

void SErrorHandler	(	int	level,
		Bool_t	abort,
		const char *	location,
		const char *	message
	)

Function printing log messages from ROOT.

This function is the "SFrame version" of DefaultErrorHandler defined in the TError.h header. By calling

SetErrorHandler( SErrorHandler )

somewhere at the beginning of the application, we can channel all ROOT messages through our own message logging facility.

Parameters:

level	ROOT message level
abort	Flag telling that the process should abort execution
location	The source of the message
message	The message itself

Int_t SetSErrorHandler

(

)

The following code makes sure that SetErrorHandler(SErrorHandler) is called when loading the SFrameCore library. This way all ROOT messages get printed using SLogger on the PROOF workers from the moment the SFrame libraries are loaded. (This is one of the first things that the workers do...)

I "stole" the idea for this kind of code from RooFit actually...
