Method Detail

notify

public static <L> void notify(Class<L> listenerType,
                              boolean asSystem,
                              Consumer<L> notification)

Safely send a notification to all listeners of a given type.

Only suitable for listener methods which do not throw checked or otherwise documented exceptions.

Type Parameters:

L - the type of listener

Parameters:

listenerType - the type of listener

asSystem - whether to impersonate ACL.SYSTEM2. For most listener methods, this should be true, so that listener implementations can freely perform various operations without access checks. In some cases, existing listener interfaces were implicitly assumed to pass along user authentication, because they were sometimes triggered by user actions such as configuration changes; this is an antipattern (better to pass an explicit Authentication argument if relevant).

notification - a listener method, perhaps with arguments
