- ## Constructor Details

  - ### AbstractKernelBasedComponent

    public AbstractKernelBasedComponent()

- ## Method Details

  - ### getComponentVersion

    public String getComponentVersion()

  - ### getKernel

    public Kernel getKernel()

  - ### initBindings

    public void initBindings(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

    public void updateServiceEntity()
    Overrides:
      `updateServiceEntity` in class `BasicComponent`

  - ### createScriptEngineManager

    protected ScriptEngineManager createScriptEngineManager()
    Overrides:
      `createScriptEngineManager` in class `BasicComponent`

  - ### registerModules

    protected abstract void registerModules(Kernel kernel)
