#logger=(new_logger) ⇒ Object

Allows to change the logger object at this level of the hierarchy

This is usually not used directly: a new logger can be created with Hierarchy#make_own_logger and removed with Hierarchy#reset_own_logger

    @logger = new_logger
    each_log_child do |child|
        child.reset_default_logger
    end
end

#make_own_logger(new_progname = nil, new_level = nil) ⇒ Object

Makes it so that this level of the module hierarchy has its own logger. If new_progname and/or new_level are nil, the associated value are taken from the parent’s logger.

    @__utilrb_hierarchy__default_logger = nil
    each_log_child do |child|
        child.reset_default_logger
    end
end

#reset_own_logger ⇒ Object

Removes a logger defined at this level of the module hierarchy. The logging methods will now access the parent’s module logger.
