If there is a job with an updated {@link DirectJobStatus status}, the returned object contains
necessary information to act on the status change. The returned object can be queried using
{@link DirectJobStatusResponse#is(DirectJobStatus) .is(}{@link DirectJobStatus#NO_CHANGES NO_CHANGES)}
to determine if there has been a status change. When processing of the status change is complete, (e.g. retrieving
{@link #getPAdES(PAdESReference) PAdES} and/or {@link #getXAdES(XAdESReference) XAdES} documents for a
{@link DirectJobStatus#COMPLETED_SUCCESSFULLY completed} job where all signers have {@link SignerStatus#SIGNED signed} their documents,
the returned status must be {@link #confirm(DirectJobStatusResponse) confirmed}.
<p>
Only jobs with {@link DirectJob.Builder#retrieveStatusBy(StatusRetrievalMethod) status retrieval method} set
to {@link StatusRetrievalMethod#POLLING POLLING} will be returned.

@return the changed status for a job, or an instance indicating {@link DirectJobStatus#NO_CHANGES no changes},
never {@code null}.
