    • start

      public void start()

    • getBundleId

      public Long getBundleId()

    • reference

    • configureComponentHolder

      public boolean configureComponentHolder(ComponentHolder<?> holder)
      The return value is only relevant for the call from configurationEvent(ConfigurationEvent) in the case of a deleted configuration which is not a factory configuration!

    • configurationEvent

      public void configurationEvent(org.osgi.service.cm.ConfigurationEvent event)
      Called by the Configuration Admin service if a configuration is updated or removed.

      This method is really only called upon configuration changes; it is not called for existing configurations upon startup of the Configuration Admin service. To bridge this gap, the

      invalid reference 
      ComponentRegistry#serviceChanged(org.osgi.framework.ServiceEvent)
      method called when the Configuration Admin service is registered calls #configureComponentHolders which calls this method for all existing configurations to be able to forward existing configurations to components.
      Parameters:
      event - The configuration change event

    • getComponentHolders

      protected abstract Collection<ComponentHolder<?>> getComponentHolders(TargetedPID pid)

    • findSingletonConfiguration

      public org.osgi.service.cm.Configuration findSingletonConfiguration(org.osgi.service.cm.ConfigurationAdmin ca, String pid, org.osgi.framework.Bundle bundle)
      Returns the configuration whose PID equals the given pid. If no such configuration exists, null is returned.
      Parameters:
      ca - Configuration Admin service
      pid - Pid for desired configuration
      bundle - bundle of the component we are configuring (used in targeted pids)
      Returns:
      configuration with the specified Pid
