Method Detail

### processPropertyUpdate

    public void processPropertyUpdate(ContainerInstance ci,
                                      Component component,
                                      org.w3c.dom.Element propertyElement)

  Description copied from interface: `PropertyUpdateProcessor`
  Notifies the `ComponentSynchronizePeer` that a client property update has occurred.

  Specified by:
    `processPropertyUpdate` in interface `PropertyUpdateProcessor`
  Parameters:
    `ci` - the relevant `ContainerInstance`
    `component` - the target `Component`
    `propertyElement` - the XML element describing the property update (the name and value of the changed property may be obtained by querying the `PROPERTY_NAME` and `PROPERTY_VALUE` attribute values.
  See Also:
    `PropertyUpdateProcessor.processPropertyUpdate(nextapp.echo2.webcontainer.ContainerInstance, nextapp.echo2.app.Component, org.w3c.dom.Element)`

### processAction

    public void processAction(ContainerInstance ci,
                              Component component,
                              org.w3c.dom.Element actionElement)

  Description copied from interface: `ActionProcessor`
  Notifies the `ComponentSynchronizePeer` that a client action has occurred.

  Specified by:
    `processAction` in interface `ActionProcessor`
  Parameters:
    `ci` - the relevant `ContainerInstance`
    `component` - the target `Component`
    `actionElement` - the XML element describing the action (the name and value of the action may be obtained by querying the `ACTION_NAME` and `ACTION_VALUE` attribute values.
  See Also:
    `ActionProcessor.processAction(nextapp.echo2.webcontainer.ContainerInstance, nextapp.echo2.app.Component, org.w3c.dom.Element)`

### renderHtml

    public void renderHtml(RenderingContext rc,
                           org.w3c.dom.Node parentNode,
                           Component component)

  Description copied from class: `AbstractEchoPointPeer`
  This is the rendering method you must implement if you are to use `AbstractEchoPointPeer`.

  Its a simpler wrapper for the standard one but provides some neato setup services that would otherwise be repeated over and over again.

  Note the use of RenderingContext object instead of the standard Echo RenderContext as this provides more rich code facilities.

  Specified by:
    `renderHtml` in class `AbstractEchoPointPeer`
  Parameters:
    `rc` - - the RenderingContext to use
    `parentNode` - - the parent Node to put content into
    `component` - - the component in question
  See Also:
    `AbstractEchoPointPeer.renderHtml(echopointng.ui.util.RenderingContext, org.w3c.dom.Node, nextapp.echo2.app.Component)`

### createInitDirective

    protected void createInitDirective(RenderingContext rc,
                                       Calculator calc,
                                       Style fallbackStyle)

### renderDispose

    public void renderDispose(RenderContext rc,
                              ServerComponentUpdate update,
                              Component component)

  Description copied from class: `AbstractEchoPointPeer`
  Removes any render state that is associated with the component.

  Remember to call `super.renderDispose()` if you overrride this method.

  Specified by:
    `renderDispose` in interface `ComponentSynchronizePeer`
  Overrides:
    `renderDispose` in class `AbstractEchoPointPeer`
  Parameters:
    `rc` - the relevant `RenderContext`
    `update` - the `ServerComponentUpdate` for which this operation is being performed
  See Also:
    `AbstractEchoPointPeer.renderDispose(nextapp.echo2.webcontainer.RenderContext, nextapp.echo2.app.update.ServerComponentUpdate, nextapp.echo2.app.Component)`

### createDisposeDirective

    protected void createDisposeDirective(ServerMessage serverMessage,
                                          Component component)
