OfflineODataDelegate
public protocol OfflineODataDelegateA delegate used to get progress updates while an OfflineODataProvider is
opening, downloading, file downloading, uploading, and sending the store to server,
to get state change notifications, and to get information about requests that fail
during an upload.
-
Called every time there is an update while the
OfflineODataProvideris performing a download.Generally the SAPOfflineOData framework and mobile services communicate through a sequence of proprietary commands while performing a download. This is the typical communication when performing a download to retrieve the delta from the backend. This function updates the progress of that communication.
During the download processing, mobile services MAY decide to send a new offline store in its entirety via a file download. For progress on the file transfer itself see
offlineODataProvider(_:didUpdateFileDownloadProgress:).Declaration
