///////////////////////////////////////////////////////////////////////////////
// @File Name: Logger.h //
// @Author: Pankaj Choudhary //
// @Version: 0.0.1 //
// @L.M.D: 13th April 2015 //
// @Description: For Logging into file //
// //
// Detail Description: //
// Implemented complete logging mechanism, Supporting multiple logging type //
// like as file based logging, console base logging etc. It also supported //
// for different log type. //
// //
// Thread Safe logging mechanism. Compatible with VC++ (Windows platform) //
// as well as G++ (Linux platform) //
// //
// Supported Log Type: ERROR, ALARM, ALWAYS, INFO, BUFFER, TRACE, DEBUG //
// //
// No control for ERROR, ALRAM and ALWAYS messages. These type of messages //
// should be always captured. //
// //
// BUFFER log type should be use while logging raw buffer or raw messages //
// //
// Having direct interface as well as C++ Singleton inface. can use //
// whatever interface want. //

// @File Name: Logger.cpp //
// @Author: Pankaj Choudhary //
// @Version: 0.0.1 //
// @L.M.D: 13th April 2015 //
// @Description: For Logging into file //
// //
// Detail Description: //
// Implemented complete logging mechanism, Supporting multiple logging type //
// like as file based logging, console base logging etc. It also supported //
// for different log type. //
// //
// Thread Safe logging mechanism. Compatible with VC++ (Windows platform) //
// as well as G++ (Linux platform) //
// //
// Supported Log Type: ERROR, ALARM, ALWAYS, INFO, BUFFER, TRACE, DEBUG //
// //
// No control for ERROR, ALRAM and ALWAYS messages. These type of messages //
// should be always captured. //
// //
// BUFFER log type should be use while logging raw buffer or raw messages //
// //
// Having direct interface as well as C++ Singleton inface. can use //
// whatever interface want. //
