    - #### kernel

          protected Kernel kernel

  - ### Constructor Detail

    - #### AbstractKernelBasedComponent

          public AbstractKernelBasedComponent()

  - ### Method Detail

    - #### getComponentVersion

          public java.lang.String getComponentVersion()

    - #### getKernel

          public Kernel getKernel()

    - #### initBindings

          public void initBindings​(javax.script.Bindings binds)

      Description copied from class: `BasicComponent`
      Initialize a mapping of key/value pairs which can be used in scripts loaded by the server
      Overrides:
        `initBindings` in class `BasicComponent`
      Parameters:
        `binds` - A mapping of key/value pairs, all of whose keys are Strings.

    - #### start

          public void start()

      Specified by:
        `start` in interface `MessageReceiver`
      Overrides:
        `start` in class `AbstractMessageReceiver`

    - #### isDiscoNonAdmin

          public abstract boolean isDiscoNonAdmin()

      Is this component discoverable by disco#items for domain by non admin users.
      Returns:
        `true` - if yes

    - #### processPacket

          public void processPacket​(Packet packet)

      Description copied from class: `AbstractMessageReceiver`
      This is the main `Packet` processing method. It is called concurrently from many threads so implementing it in thread save manner is essential. The method is called for each packet addressed to the component.
      Please note, the `Packet` instance may be processed by different parts of the server, different components or plugins at the same time. Therefore this is very important to tread the `Packet` instance as unmodifiable object.
      Processing in this method is asynchronous, therefore there is no result value. If there are some 'result' packets generated during processing, they should be passed back using `addOutPacket(Packet)` method.
      Specified by:
        `processPacket` in class `AbstractMessageReceiver`
      Parameters:
        `packet` - is an instance of the `Packet` class passed for processing.

    - #### register

          public void register​(Kernel kernel)

      Description copied from interface: `RegistrarBean`
      Method called when bean is being registered allowing developer to programatically register other beans.
      Specified by:
        `register` in interface `RegistrarBean`
      Parameters:
        `kernel` - - instance from local scope

    - #### unregister

          public void unregister​(Kernel kernel)

      Description copied from interface: `RegistrarBean`
      Method called while bean is being unregistered.
      Specified by:
        `unregister` in interface `RegistrarBean`
      Parameters:
        `kernel` - - instance from local scope

    - #### updateServiceEntity
