Description

Hello. How to work with delta responses of OData 4.0. For OData 4.0 no documentation that describes the work with delta responses.

I am interested in how to get deleted link and deleted entries?

In the old version, this can be done as follows:

ODataFeed feed = client.readFeed("Container1", "Rooms", contentType);
String deltaLink = feed.getFeedMetadata().getDeltaLink();

ODataDeltaFeed deltaFeed = client.readDeltaFeed("Container1", "Rooms", contentType, deltaLink);
List<ODataEntry> changedEntries = deltaFeed.getEntries();
List<DeletedEntryMetada) deletedEntries = deltaFeed.getDeletedEntries();

How to do this for the OData 4.0 using the new library?

I have tried the this:

ClientDelta delta = client.getObjectFactory().newDelta();
LogUtil.d("qwerty","" + delta.getAddedLinks());

but this code always returns an empty string.

I am waiting for an answer. Thank you .
