------------------------------------
Hello Chandan,
thank you for the clarification and the code sample. We do not use the JPA
Processor, but I can use the code as a reference.
I've noticed that your code assumes that $skiptoken is an Integer. Does this
mean you use $skiptoken to indicate the n-th value you want the page to start
with, rather than to indicate the key of the entry with which the page should
start?
We are intending to use $skiptoken in the same way, but I am worried that this
might not be aligned with the OData 2.0 specification.
Thanks
Miki

> Hello,
> I use $skiptoken to implement pagination in my service. What should the
> service return when $skiptoken is used in conjunction with $top and $skip?
> Should the numbers specified in $top and $skip be considered relative to the
> starting point of the page being displayed or should they be considered
> absolute values?
> For example, if I have $skiptoken=10&$top=4 should the service return the
> first 4 items of the page starting with entry number 10 or should the service
> return nothing because $skiptoken > $top? If the latter is true, then to
> obtain the first 4 entres on the second page one would have to specify
> $skiptoken=10&$top=14. Which is correct?
> Similarly, if I have $skiptoken=10&$skip=2, should the service return the
> entres on the page starting with element 10 but skipping the first 2 entres?
> Lastly, I understand that $skiptoken should represent the id of the first
> entry to display on a page. What should the id be for entities with compound
> keys (i.e. a name and a date)?
> Cheers
> Miki
