    public static final class MultiplexedSessionPrecommitToken.Builder extends GeneratedMessage.Builder<MultiplexedSessionPrecommitToken.Builder> implements MultiplexedSessionPrecommitTokenOrBuilder

When a read-write transaction is executed on a multiplexed session,
this precommit token is sent back to the client
as a part of the Transaction message in the
BeginTransaction response and
also as a part of the ResultSet and
PartialResultSet responses.
