Description copied from interface: JwtRetriever

Retrieves a JWT access token in its serialized three-part form. The implementation is free to determine how it should be retrieved but should not perform validation on the result. Note: This is a blocking function and callers should be aware that the implementation may be communicating over a network, with the file system, coordinating threads, etc. The facility in the LoginModule from which this is ultimately called does not provide an asynchronous approach.

Specified by:

retrieve in interface JwtRetriever

Returns:

Non-null JWT access token string

Throws:

JwtRetrieverException - Thrown on errors related to IO during retrieval
