Archana Rai commented on OLINGO-953:
------------------------------------
Can you share the logic within your pushDeletedData(url);
If you have a single entity within the Categories entittSet still the
ClientEntitySet should not get null, instead it should get the Object without
any entity.
After which you should be able to do this:
ODataDeltaRequest products=
client.getRetrieveRequestFactory().getDeltaRequest(products.getDeltaLink());
deltaReq.setFormat(format);
ClientDelta delta = deltaReq.execute().getBody();
delta.getDeletedEntities()
Thanks,
Archana

> Project: Olingo
> Issue Type: Question
> Components: odata4-client
> Affects Versions: (Java) V4 4.0.0-beta-03
> Reporter: Konstantin Kustov Sergeevich
> Labels: android-studio, java
>
> 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 :).
