Is Datastax UUIDs a wrapper for java.util.UUID

If I don't encode UUIDs.timeBased() before inserting in a dataframe, I get the following Exception:

java.lang.UnsupportedOperationException: No Encoder found for java.util.UUID

So, instead of encoding, can I simply use UUIDs.timeBased().toString() before inserting into a dataframe (and subsequently Cassandra)?
And, if I need to parse a timestamp during a later data query, use java.util.UUID.fromString(myUUIDSavedAsStringInCassandra)?

Declare the column type as `timeuuid` – Ashraful Islam Apr 22 '18 at 08:59
thanks....an exact duplicate indeed. Glad you found this – Jake Apr 22 '18 at 16:56
so YES it is a wrapper and YES it is OK to convert to String for dataframes (according to related question labeled above ) – Jake Apr 22 '18 at 17:02
