Detailed Description

A helper class for logging messages using the "<<" operator.

Each instance of the LogMessageStream class is used for logging one single message. It keeps a reference of the logger to use and a pointer of the related function (to allow different logging levels). The message is logged during the destruction of the object. Instances can only be retrieved by using the Elements::Logging::debug, Elements::Logging::info, etc methods.
