To load view model to view mappings from the extension point, call Renderer.loadMappings(String).

Specified by:

initialize in interface IRenderer<LwtRenderingParameters>

Overrides:

initialize in class Renderer<ILightControl,LwtRenderingParameters>

Parameters:

parameters - the renderer parameters.

relayout

public void relayout()

Description copied from interface: IRenderer

Triggers layout processing.

render

public void render(Iterable<IViewModel> viewModels)

Description copied from interface: IRenderer

Renders the provided view models.

Parameters:

viewModels - the view models to render.

dispose

public void dispose()

Description copied from interface: IRenderer

Disposes this renderer.

createLightControl

protected <VM extends IControlViewModel> ILightControl createLightControl(IView<LwtRenderingParameters,VM,ILightControl> view,
                                                                          VM viewModel,

Parameters:

lightControl - the light control to dispose.

getTargetId

protected String getTargetId()

This identifier will be used to obtain view model to view mappings from the extension point in Renderer.loadMappings(String).

Examples:

• swt
• lwt

Specified by:

getTargetId in class Renderer<ILightControl,LwtRenderingParameters>

Returns:

the target id

viewCanBeReused

protected boolean viewCanBeReused(IView<?,?,?> view,
                                  IViewModel oldViewModel,
                                  IViewModel newViewModel)
