Framework Logger File
This API provides all functionnalities necessary to log text and data to different targets, allowing to select only relevant log items categories, log types and source objects throught appropriate filters. It is possible to choose log items properties from more than 10 ones (including information about the caller: object, type, method / property name,source file name and line number) and to control the formating of log items texts (formating,order and size of columns). Several standard loggers are provided, but new ones can be developped in a very simple way. Each component can also be extended in order to support new functionnalities. The API is designed to run fast. Filters and formating can be controlled in a global way or individualy for each logger. It can store items in real time and delivers it in a deferred way by blocks. It supports multithreading contexts.
