Detailed Description

Message streamer.

This class can be used in the same way as the STL ostream operator.
The actual message is reported on detruction of the object, e.g:

JStreamLogger logger(std::cout);

JDebugStream (logger) << "This is a debug message " << hex << 15;

will produce on the terminal:

"... This is a debug message f"

where ... stands for the message prefix (see class JMessageLogger). The list of available message streamer classes includes:

• JDebugStream
• JWarningStream
• JErrorStream
• JNoticeStream
• JStatusStream
