unsetPriority

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


unsetPriority

public void unsetPriority(boolean recursive)

Unset the logtargets for this logger. This logger (and thus all child loggers who don't specify logtargets) will inherit from the parents LogTargets.


unsetLogTargets

public void unsetLogTargets(boolean recursive)
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.
