Does Olingo 4 support delta link?

[Mikael Thyman <mi...@mblox.com>]

Hi,

I'm adding server side paging to our Olingo 4.2.0 OData service and I've
run into some issues with the delta link.

First, I add the delta link by using entitySet.setDeltaLink(); but there's
no @odata.deltaLink present in the response.

If I try to use my delta link then Olingo doesn't recognize the $deltaToken
query option (The system query option '$deltaToken' is not defined."}}) nor
does UriInfo provide any method for reading the deltaToken as it does for
the skipToken (uriInfo.getSkipTokenOption()).

Does Olingo 4 support delta links or is there something else that I need to
do to get it working?

Thanks!

Mikael, 

Olingo does not support "metadata=full" payload yet, so I suspect that is one reason behind it. I myself have not done any delta link stuff, I have to say Olingo does not support it yet. So, I suggest opening a JIRA, and this would be an excellent feature for if you want contribute towards next 4.3 release. 

We will help however we can.
