class RooMsgService: public TObject
The RooMsgService class is a singleton class that organizes informational, debugging, warning and errors messages generated by the RooFit core code.

Each message generated by the core has a message level (DEBUG,INFO,PROGRESS,WARNING,ERROR or FATAL), an originating object, and a 'topic'. Currently implemented topics are "Generation","Plotting", "Integration", "Minimization" and "Workspace" and "ChangeTracking".

The RooMsgService class allows to filter and redirect messages into 'streams' according to message level, topic, (base) class of originating object, name of originating object and based on attribute labels attached to individual objects.

The current default configuration creates streams for all messages at WARNING level or higher (e.g. ERROR and FATAL) and for all INFO message on topics Generation,Plotting, Integration and Minimization and redirects them to stdout. Users can create additional streams for logging of e.g. DEBUG messages on particular topics or objects and or redirect streams to C++ streams or files.

The singleton instance is accessible through RooMsgService::instance() ;

Function documentation

void cleanup()
 Cleanup function called by atexit() handler installed by RooSentinel
 to delete all global object upon program termination
RooMsgService(const RooMsgService& )
 Constructor. Defines names of message levels
 and mapping of topic codes to topic names
 Install default message streams.
~RooMsgService()
 Destructor
Bool_t anyDebug()
 Returns true if any debug level stream is active
Int_t addStream(RooMsgService::MsgLevel level, const RooCmdArg& arg1 = RooCmdArg(), const RooCmdArg& arg2 = RooCmdArg(), const RooCmdArg& arg3 = RooCmdArg(), const RooCmdArg& arg4 = RooCmdArg(), const RooCmdArg& arg5 = RooCmdArg(), const RooCmdArg& arg6 = RooCmdArg())
 Add a message logging stream for message with given MsgLevel or higher (i.e. more severe)
 This method accepts the following arguments to configure the stream

 Output Style options

 ClassName(const char*)    -- Restrict stream to messages from objects with given class name
 BaseClassName(const char*)-- Restrict stream to messages from objects with given base class name
 LabelName(const chat*)    -- Restrict stream to messages from objects setAtrribute(const char*) tag with given name

 Output redirection options

 OutputFile(const char*)  -- Send output to file with given name. Multiple streams can write to same file.
 OutputStream(ostream&)   -- Send output to given C++ stream. Multiple message streams can write to same c++ stream

 The return value is the unique ID code of the defined stream
