protected Connect.LoadStyle getLoadStyle(Class<? extends ServerConnector> connector)
- 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
Connect
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
