Method	copyTo	Copy the contents of this dirdbm to the dirdbm at `path`.
Method	clear	Delete all key/value pairs in this dirdbm.
Method	close	Close this dbm: no-op, for dbm-style interface compliance.
Method	getModificationTime	Returns modification time of an entry.
Method	_encode	Encode a key so it can be used as a filename.
