Hi!
Have you checked its source? Here's the 5.1.0.5 one (which is the version
used in the project I'm working now):
public class MultiZoneUpdateEventResultProcessor implements
ComponentEventResultProcessor<MultiZoneUpdate>
{
private final PageRenderQueue queue;
private final TypeCoercer typeCoercer;
public MultiZoneUpdateEventResultProcessor(PageRenderQueue queue,
TypeCoercer typeCoercer)
{
this.queue = queue;
this.typeCoercer = typeCoercer;
}
public void processResultValue(final MultiZoneUpdate value) throws
IOException
{
// There has to be at least a single command in the queue to force
a render.
queue.initializeForPartialPageRender(new RenderCommand()
{
public void render(MarkupWriter writer, RenderQueue queue)
{
}
});
queue.addPartialMarkupRendererFilter(new SetupZonesFilter());
Map<String, Object> map = value.getZoneToRenderMap();
for (String zoneId : map.keySet())
{
Object provided = map.get(zoneId);
RenderCommand zoneRenderCommand = toRenderer(zoneId, provided);
queue.addPartialMarkupRendererFilter(new
SingleZonePartialRendererFilter(zoneId, zoneRenderCommand, queue));
}
}
private RenderCommand toRenderer(String zoneId, Object provided)
{
try
{
return typeCoercer.coerce(provided, RenderCommand.class);
}
catch (Exception ex)
{
throw new IllegalArgumentException(String.format("Failure
converting renderer for zone '%s': %s",
zoneId,
InternalUtils.toMessage(ex)),
ex);
}
}
}
