Method Details

afterCreate

public void afterCreate(Component[] comps)

Description copied from interface: UiEngineImpl.Extension

Called after the whole component tree has been created by this engine.

The implementation might implement this method to process the components, such as merging, if necessary.

Specified by:

afterCreate in interface UiEngineImpl.Extension

Parameters:

comps - the components being created. It is never null but it might be a zero-length array.

afterRenderComponents

public void afterRenderComponents(Collection comps)

Description copied from interface: UiEngineImpl.Extension

Called when this engine renders the given components. It is designed to be overridden if you'd like to alter the component and its children after they are rendered.

Specified by:

afterRenderComponents in interface UiEngineImpl.Extension

Parameters:

comps - the collection of components that have been redrawn.

afterRenderNewPage

public void afterRenderNewPage(Page page)

Description copied from interface: UiEngineImpl.Extension

Called after a new page has been redrawn (PageCtrl.redraw(java.io.Writer) has been called).

Notice that it is called in the rendering phase (the last phase), so it is not allowed to post events or to invoke invalidate or smartUpdate in this method.

Notice that it is not called if an old page is redrawn.

The implementation shall process the components such as merging if necessary.

Specified by:

afterRenderNewPage in interface UiEngineImpl.Extension
