Method Details

accept

void accept(T t,
 Introspection introspection)

Executed when the subscribed to FrameworkEvent (T) is published by the framework.

Inside this method you can always use Introspection.accessScoped() and Introspection.scopedGet(Property), the returned Introspection instance is the one that was used to publish the event. Thus, the stage of the Introspection is depending on the used FrameworkEvent. You can take a look at the specific IntrospectionAccess annotation of an FrameworkEvent class to know which stage is available.

This method will be executed in different threads, thus the logic inside needs to be threadsafe!

Specified by:

accept in interface BiConsumer<T extends FrameworkEvent, Introspection>

Parameters:

t - the published FrameworkEvent

introspection - the Introspection instance used to publish this event.
