Dan,
The Controls Programming Tutorial is a bit-of-date when it comes to resource
events. Steve Hansen is working on updating the docs on the site, and when
the content is refreshed this particular area will be fixed.
It is possible to get resource events, but instead of these being events on the
ControlBeanContext, there is instead a separate context (ResourceContext) that
provides resource notifications. The rationale for this is that it enables
the easy identification of controls that need resource events (and thus a
container that provides a notion of resource scope) from ones that do not
(basic JavaBeans).
A control impl can get these events by simply declaratively defining a
ResourceContext instance, as follows:
@Context org.apache.beehive.controls.context.ResourceContext
resourceContext;
Then it uses the exact same syntax as you show below, but as a ResourceContext
event instead of a ControlBeanContextEvent:
@EventHandler (field="resourceContext",
eventSet=ResourceContext.ResourceEvents.class, eventName="onAcquire")
/* package */ void onAcquire()
{
...
}
@EventHandler (field="resourceContext",
eventSet=ResourceContext.ResourceEvents.class, eventName="onRelease")
protected void onRelease()
{
...
}
The Controls tests contains a sample bean that tests resource events at:
