This is an SQLite-based specialization of SQLStore.

To create an instance, see SQLStore.__init__. To create the tables it will use, see SQLStore.createTables.

All other methods are implementation details.

Instance Methods [hide private]
  blobDecode(self, buf)
Convert a blob as returned by the SQL engine into a str object.
  blobEncode(self, s)
Convert a str object into the necessary object for storing in the database as a blob.
bool useNonce(self, *args, **kwargs)
Return whether this nonce is present, and if it is, then remove it from the set.
