20\ingroup Roofitcore
21
22
23The class RooMsgService is a singleton that organizes messages generated in RooFit.
24Each message has a message level RooFit::MsgLevel (DEBUG,INFO,PROGRESS,WARNING,ERROR or FATAL),
25an source object, and a RooFit::MsgTopic.
26RooMsgService allows to filter and redirect messages into streams
27according to message level, topic, (base) class of originating object, name of originating
28object and based on attribute labels attached to individual objects.
29The current default configuration creates streams for all messages at WARNING level
30or higher (e.g. ERROR and FATAL) and for all INFO message on topics Generation,Plotting,
31Integration and Minimization and redirects them to stdout. Users can create additional streams
32for logging of e.g. DEBUG messages on particular topics or objects and/or redirect streams to
33C++ streams or files.
34
35The singleton instance is accessible through RooMsgService::instance().
36
37### Temporarily change the message level
38There is a helper, RooHelpers::LocalChangeMsgLevel, that overrides the default message levels as
39long as it is alive. To suppress everything below WARNING:
40~~~{.cpp}
41RooHelpers::LocalChangeMessageLevel changeMsgLvl(RooFit::WARNING);
42[ statements that normally generate a lot of output ]
43~~~
44
45#### Temporarily capture a message stream
46RooHelpers::HijackMessageStream allows to fully capture a message stream in a std::stringstream. With this,
47RooFit messages can be evaluated or suppressed.
