cas
public long cas()Returns the new CAS value of the document after it has been modified successfully.The CAS value is an opaque identifier which is associated with a specific state of the document on the server. It can be used during a subsequent mutation to make sure that the document has not been modified in the meantime.
If document on the server has been modified in the meantime the SDK will raise a
CasMismatchException. In this case the caller is expected to re-do the whole "fetch-modify-update" cycle again. Please refer to the SDK documentation for more information on CAS mismatches and subsequent retries. -
mutationToken
Returns theMutationTokenof the document after the performed mutation.Note that this value is only present if mutation tokens have been enabled on the environment configuration.
