public class EagerWidgetMapGenerator
extends WidgetMapGenerator

WidgetMap generator that builds a widgetset that packs all included widgets into a single JavaScript file loaded at application initialization. Initially loaded data will be relatively large, but minimal amount of server requests will be done.

This is the default generator in version 6.4 and produces similar type of widgetset as in previous versions of Vaadin. To activate "code splitting", use the WidgetMapGenerator instead, that loads most components deferred.

Method Detail

getLoadStyle

protected ClientWidget.LoadStyle getLoadStyle(Class<? extends Paintable> paintableType)

Description copied from class: WidgetMapGenerator

Returns true if the widget for given component will be lazy loaded by the client. The default implementation reads the information from the ClientWidget annotation.

The method can be overridden to optimize the widget loading mechanism. If the Widgetset is wanted to be optimized for a network with a high latency or for a one with a very fast throughput, it may be good to return false for every component.

Overrides:
getLoadStyle in class WidgetMapGenerator

Returns:
true iff the widget for given component should be lazy loaded by the client side engine
