  • Method Details

    • dispatch

      void dispatch(boolean ignoreVersion, boolean allowNotFound, OperationResult result) throws SchemaException
      Dispatches information on system configuration object change. Basically this directly pushes information to lower layers (prism, schema, repo, etc), and calls registered listeners that originate in upper layers.
      Parameters:
      ignoreVersion - If false, the information is dispatched unconditionally. If true, we dispatch the notification only if the system configuration version was really changed. This is to easily support sources that "ping" sysconfig object in regular intervals, e.g. the cluster manager thread.
      allowNotFound - If true, we take non-existence of sysconfig object more easily. To be used e.g. on system init or during tests execution.
      Throws:
      SchemaException
    • registerListener

      void registerListener(SystemConfigurationChangeListener listener)
      Registers a listener that will be updated on system configuration object changes.
    • unregisterListener

      void unregisterListener(SystemConfigurationChangeListener listener)
      Unregisters a listener.
