    • Method Detail

      • init

        public void init()
        Initializes the log manager. This internally executes the following:
        • Track all bundles for retrieving the log levels of each bundles if the log extension is (ds.log.extension) not set or set to false (log extension disabled)
        • Don't track any bundles if log extension is enabled since we don't need the log levels of the respective bundles. For log extension, we use the log level of the SCR bundle itself.
        • Start the service tracker to track the OSGi LoggerFactory service

      • addingService
