Configuration dependency that can track the availability of a (valid) configuration. To use it, specify a PID for the configuration. The dependency is always required, because if it is not, it does not make sense to use the dependency manager. In that scenario, simply register your service as a
ManagedService(Factory) and handle everything yourself. Also, only managed services are supported, not factories. There are a couple of things you need to be aware of when implementing the
updated(Dictionary) method:
- Make sure it throws a
ConfigurationException when you get a configuration that is invalid. In this case, the dependency will not change: if it was not available, it will still not be. If it was available, it will remain available and implicitly assume you keep working with your old configuration. - This method will be called before all required dependencies are available. Make sure you do not depend on these to parse your settings.
