// Thread safe logger (except for set_pattern(..), set_formatter(..) and set_error_handler())
|
|
// Has name, log level, vector of std::shared sink pointers and formatter
|
|
// Upon each log write the logger:
|
|
// 1. Checks if its log level is enough to log the message
|
|
// 2. Format the message using the formatter function
|
|
// 3. Pass the formatted message to its sinks to performa the actual logging
