writeProperties() complements readProperties(). It is identical to calling setProperty() for each individual entry, which is also the default implementation. Some ConfigNode implementations can implement this more efficiently. clear() goes beyond repeated removeProperty() calls because it can also wipe out everything else which might have ended up in the node (for example, comments in the .ini format).
