Define Documentation

#define LOG_LEVEL ( classname   )     public: enum log_level_enums { __VA_ARGS__ }; log_level_template<classname> log_level; private: friend class log_level_intermediate<classname>; static const Array<string> &log_level_names() { static const Array<string> log_level_names = log_level_template<classname>::string2Array( #__VA_ARGS__ ); return log_level_names; }

Macro for defining a log_level attribute with a specific set of enumerations related to a specific class.

This macro has to be called within a class declaration. Its argument classname has to correspond to that wrapping class. This macro defines a log_level instance which can be modified either directly or by the means of bdm::UI class.

One of the main purposes of this macro is to allow variability in using enumerations. By relating them to their names through an array of strings, we are no more dependant on their precise ordering. What is more, we can add or remove any without harming any applications which are using this library.
