Hi Thomas,
thank you for the example. I will certainly go into the specifications in
more detail.
What I need is a component that collects all the services that will then be
used in the bundle.
When all services are available, the bundle starts all bootstrap operations
and starts processing logic.
If a service (of another bundle) updates itself,
I would like this service collector to update its reference without
reactivating.
If I have understood well the combination of properties that allows me to
obtain
this is: policy = DYNAMIC, policyOption = GREEDY, cardinality = MULTIPLE and
@Component (immediate = true).
EXAMPLE:
@Component
public class AImpl implements A {}
@Component
public class BImpl implements B {}
@Component(immediate = true)
public class ServicesCollector {
private A a;
private B b;
private Bootstrap boostrap;
@Activate
public void activate(BundleContext bundleContext) {
boostrap.start();
}
@Deactivate
public void deactivate() {
boostrap.stop();
}
@Reference(cardinality = ReferenceCardinality.MULTIPLE,
policy = ReferencePolicy.DYNAMIC,
policyOption = ReferencePolicyOption.GREEDY)
public void setA(A a) {this.a = a}
public void unsetA(A a) {}
@Reference(cardinality = ReferenceCardinality.MULTIPLE,
policy = ReferencePolicy.DYNAMIC,
policyOption = ReferencePolicyOption.GREEDY)
public void setB(B b) {this.b = b}
public void unsetB(B a) {}
}
Are there no other options right? thanks for your helps.
Kind regards,
Marco
