Detailed Description

Adapts mi::base::ILogger to a standard streaming interface.

Messages are forwarded to the logger whenever the stream is flushed. The log level for the next message can be changed by using one of the manipulators fatal, error, warning, info, verbose, or debug, which correspond to the values of mi::base::details::Message_severity. The log details can be changed by pushing an instance of mi::base::details;:Message_details into the stream. Changing the log level or the details also triggers flushing.

Example:

mi::base::Handle<mi::base::Logger> logger( ...);
mi::base::Log_stream stream( logger.get(), "APP:MAIN");
stream << "An info message" << std::flush;
stream << error << "And an error message" << std::flush;
stream << "And another info message" << std::flush;
