Re: [osgi-dev] Order of injected services into a Collection/List field

The ordering is the same regardless of whether the reference is static or dynamic.
 
I have clarified the text in 112.3.8.1 for this in the DS 1.4 spec.

Hi,DS 1.3 added field injection and now supports Collections/Lists. Unfortunately it is only specified (in OSGi R6 Comp, §112.3.8.1) how those are ordered in case of dynamic references. What about having a static reference with multiple cardinality?I fail to see the according spec about the ordering of these.Is this an oversight on my side, or is this just missing from the spec?Can I assume that those are ordered as well according to ServiceReference.compareTo(...)?Thanks,Konrad___OSGi Developer Mail Listosgi-dev@mail.osgi.orghttps://mail.osgi.org/mailman/listinfo/osgi-dev

However there is a caveat. If you use the UPDATE field strategy, supplying
your own collection or map implementation then ordering is up to you.

Actually it is not the reversed natural ordering but the natural ordering (i.e. 
lowest ranked first!), see 112.3.8.1 in OSGi 6 Compendium
"Before the component instance is activated, SCR must set the field with
a new mutable collection that must contain the initial set of bound services 
sorted using the same
ordering as ServiceReference.compareTo based upon service ranking and service 
id."

Hi Ray,
thats what I assume as well, but I couldn't find that explicitly specified in 
DS 1.3. If I did not oversee that it would be IMHO good to explicitly state 
that in the DS 1.4 Spec. WDYT?
What is the process of getting an issue resolved in a newer spec version?
Thanks,
Konrad

Re: [osgi-dev] Order of injected services into a Collection/List field

2017-03-09 Thread Raymond Auge 
I do believe the order is always reversed natural ordering on the
ServiceReference.

i.e.
- first; ordered by service.ranking property in descending order (highest
ranked first)
- second; ordered by service.id property in ascending order (oldest first)

HTH,
