      Returns:
      true if there is a Fault.

    • updateReferenceFilter

      static boolean updateReferenceFilter(org.osgi.service.cm.ConfigurationAdmin cm, String pid, String member, String... ids)
      Sets a target filter for a Declarative Service @Reference member.

      Usage: 

       updateReferenceFilter(config.service_pid(), "Controllers", controllersIds);

      Generates a 'target' filter on the 'Controllers' member so, that the the expected service to be injected needs to fulfill:

      • the service must be enabled
      • the service must not have the same PID as the calling component
      • the service "id" must be one of the provided "controllersIds"
      Parameters:
      cm - a ConfigurationAdmin instance. Get one using 
                     @Reference
               ConfigurationAdmin cm;
      pid - PID of the calling component (use 'config.service_pid()' or '(String)prop.get(Constants.SERVICE_PID)'; if null, PID filter is not added to the resulting target filter
      member - Name of the Method or Field with the Reference annotation
      ids - Component IDs to be filtered for; for empty list, no ids are added to the target filter
      Returns:
      true if the filter was updated. You may use it to abort the activate() method.

    • updateReferenceFilterRaw

      static boolean updateReferenceFilterRaw(org.osgi.service.cm.ConfigurationAdmin cm, String pid, String member, String filter)
      Sets a target filter for a Declarative Service @Reference member.

      Use this method only if you know what you are doing. Usually you will want to use the updateReferenceFilter(ConfigurationAdmin, String, String, String...) method instead.

      Usage: 

       updateReferenceFilterRaw(config.service_pid(), "Controllers", "(enabled=true)");
      Parameters:
      cm - a ConfigurationAdmin instance. Get one using 
                     @Reference
               ConfigurationAdmin cm;
      pid - PID of the calling component (use 'config.service_pid()' or '(String)prop.get(Constants.SERVICE_PID)'; if null, PID filter is not added to the resulting target filter
      member - Name of the Method or Field with the Reference annotation, e.g.
      filter - The filter attribute
      Returns:
      true if the filter was updated. You may use it to abort the activate() method.

    • validateSingleton

      static boolean validateSingleton(org.osgi.service.cm.ConfigurationAdmin cm, String pid, String expectedId)
      Validates and possibly fixes the Component-ID of a Singleton.

      Singleton Components are allowed to live only exactly once in an OpenEMS instance. These Components are marked with an Annotation: 

       @Designate(factory = false)

      By design it is required for these Singleton Components to have a predefined Component-ID, like '_cycle', '_sum', etc. This method makes sure the Component-ID matches this predefined ID - and if not automatically adjusts it.

      Sidenote: ideally it would be possible to use the Component Annotation 

       @Component(property = { "id=_cycle" })

      for this purpose. Unfortunately this is not sufficient to have the 'id' property listed in EdgeConfig, ConfigurationAdmin, etc. This is why this workaround is required.

      Usage: 

       if (OpenemsComponent.validateSingletonComponentId(this.cm, this.serviceFactoryPid(), SINGLETON_COMPONENT_ID)) {
        return;
 }
      Parameters:
      cm - a ConfigurationAdmin instance. Get one using 
                         @Reference
                   ConfigurationAdmin cm;
      pid - PID of the calling component (use 'config.service_pid()' or '(String)prop.get(Constants.SERVICE_PID)'; if null, Component-ID can not be updated.
      expectedId - The expected predefined Component-ID
      Returns:
      true if the ID was updated. You may use it to abort the activate() method.

    • updateConfigurationProperty

      static void updateConfigurationProperty(org.osgi.service.cm.ConfigurationAdmin cm, String pid, String property, Object value)
      Update a configuration property.

      Usage: 

       updateConfigurationProperty(cm, servicePid, "propertyName", "propertyValue");

      Parameters:
      cm - a ConfigurationAdmin instance. Get one using 
                       @Reference
                 ConfigurationAdmin cm;
      pid - PID of the calling component (use 'config.service_pid()' or '(String)prop.get(Constants.SERVICE_PID)'
      property - Name of the configuration property
      value - New configuration value
