I first thinking to use UUID for ensuring uniqueness of id when user
don't fix it.
But as Rupert states, this don't have to be a strong requirement for
implementations.
Do the type of the id is just a string ? Or an UriRef as it can be
considered as a "resource" ?

I'm wondering how this is best achieved in a way that ensures uniquness of
names. But a unique name would be better than the weight for which
service-ranking could be used instead.
Unique names are not required, as ServiceTracker as well as @Reference
annotations do support multiple matches for filters. In case two
TcProvider would use the same id, users would get the one with the
higher "service.ranking" injected. In case both have the same
"service.ranking" the one with the lower "service.id" is injected.
Services that are started earlier will have the lower "service.id".

Hi Florent
Rather than checking the weight you you could check the class with
getClass() but this sound like a hack as well.
Another approach would be to add a service property to the TcProvider so
you can filter by it when you want this particular one:
@Reference(name="provider", referenceInterface=**
WeightedTcProvider.class,
target="(my.very.special.one=**true)",
cardinality=**ReferenceCardinality.;**AMDATORY_UNARY,
policy=ReferencePolicy.STATIC)**,
Have a triple good day!

Hi there !
Working with multiple TcProvider I would like to get one in particular.
The way I find for now is to call :
SortedSet<WeightedTcProvider> providerList = tcManager.getProviderList();
And then iterate throw my providerList, and select the one I would like
by
his "weight".
"Weight" is really not an "user friendly" (nor reliable) property to
select something in a list imo... but I don't see any selection method
based on a name or an ID.
Do I miss something here ? Or a kind of "id" property can be imagined for
the TcProvider objects ?
Happy graph !
