      Specified by:
      getFilter in interface InstanceLifecycleListener
      Returns:
      The filter that tells the system if this listener applies to this descriptor. If this returns null then this Listener will apply to ALL descriptors.
    • lifecycleEvent

      public void lifecycleEvent(InstanceLifecycleEvent lifecycleEvent)
      Description copied from interface: InstanceLifecycleListener
      This method will be called when any lifecycle event occurs. The currently supported lifecycle events are PRE_PRODUCTION, POST_PRODUCTION and PRE_DESTRUCTION. Code should be written to allow for future events to be generated. This method should not throw exceptions
      Specified by:
      lifecycleEvent in interface InstanceLifecycleListener
      Parameters:
      lifecycleEvent - The event that has occurred, will not be null
    • configurationChanged

      public void configurationChanged()
      Description copied from interface: DynamicConfigurationListener
      This method is called when the set of descriptors in this service locator has been changed. Changes to parent service locators descriptors will not be reported. These services are called back on the thread doing the DynamicConfiguration.commit() so care should be taken to do any work quickly. Any exception thrown from this method will be ignored. A commit that failed will not be reported to this method
      Specified by:
      configurationChanged in interface DynamicConfigurationListener
