Summary: How to work with delta responses of OData 4.0
Key: OLINGO-953
URL: https://issues.apache.org/jira/browse/OLINGO-953
Project: Olingo
Issue Type: Question
Components: odata4-client
Affects Versions: (Java) V4 4.0.0-beta-03
Reporter: Konstantin Kustov Sergeevich
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 :).
