Re: [osgi-dev] Configuring reference.cardinality.minimum / reference.target via Metatypes

Yes. You need to use the correct property name: <refname>.cardinality.minimum. See 112.6.2.2 in the DS spec.

 

 

@ObjectClassDefinition

@interface MyConfiguration {

    String name;

    // this will make a property named stuff.cardinality.minimum

        // which is the minimum cardinality for the reference named "stuff".

    int stuff_cardinality_minimum default 3;

}

 

@Designate(ocd = MyConfiguration)

@Component(configurationPid = 'configurable')

class ConfigurableTest {

  @Reference(

    cardinality = ReferenceCardinality.MULTIPLE,

    policy = ReferencePolicy.DYNAMIC,

    policyOption = ReferencePolicyOption.GREEDY

  )

volatile List<IStuff> stuff

Hi,

 

I was wondering if one can configure the @Reference cardinality.minimum property of a service vie Metatypes somehow?

 

In my example (written in Xtend) I'd like to configure the minimum cardinality of 'stuff'. So is there a magic property name/pattern (like in the commented code below) that I can use in MyConfiguration  in order to achieve that?

 

@ObjectClassDefinition

annotation MyConfiguration{

        String name

        // String stuffCardinalityMinimum

}

 

@Designate(ocd = MyConfiguration)

@Component(configurationPid = 'configurable')

class ConfigurableTest{

@Reference(

cardinality = ReferenceCardinality.MULTIPLE,

policy = ReferencePolicy.DYNAMIC,

policyOption = ReferencePolicyOption.GREEDY

)

volatile List<IStuff> stuff

 

@Activate

private def void activate(MyConfiguration config){

println('''Activated: «config.name»''')

}

 

@Modified

private def void update(MyConfiguration config){

println('''Updated: «config.name»''')

}

 

@Deactivate

private def void deactivate(){

println('''Deactivated''')

}

}

 

@Component

class Stuff implements IStuff{}

 

interface IStuff{}

 

Any advice is appreciated :)

 

Kind regards,

Thomas
