RooMsgService Class Reference

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() ;

Add a message logging stream for message with given RooFit::MsgLevel or higher (i.e.

more severe) This method accepts the following arguments to configure the stream

Output Style options

Prefix(Bool_t flag=kTRUE) – Prefix all messages in this stream with Topic/Originator information

Filtering options

Topic(const char*) – Restrict stream to messages on given topic ObjectName(const char*) – Restrict stream to messages from object with given name 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
