      • unsetPriority

        @Deprecated() void unsetPriority()

        Unset the priority of Logger. (Thus it will use it's parent's priority or DEBUG if no parent.

      • unsetPriority

        @Deprecated() void unsetPriority(boolean recursive)

        Unset the priority of Logger. (Thus it will use it's parent's priority or DEBUG if no parent. If recursive is true unset priorities of all child loggers.

        recursive - true to unset priority of all child loggers

      • unsetLogTargets

        @Deprecated() void unsetLogTargets()

        Unset the logtargets for this logger and all child loggers if recursive is set. The loggers unset (and all child loggers who don't specify logtargets) will inherit from the parents LogTargets.
