- All Implemented Interfaces:
CallbackHandler
A Client callback handler for a WorkerToken. In general a client that wants to support worker tokens should first check if a WorkerToken
is available for the specific connection type by calling findWorkerTokenInSubject. If that returns a token, then proceed to create and
use this with a DIGEST-MD5 SaslClient. If not you should fall back to whatever other client auth you want to do.
