[jira] [Updated] (JCR-3586) NonExternalEventListener marker interface

     [ https://issues.apache.org/jira/browse/JCR-3586?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jukka Zitting updated JCR-3586:
-------------------------------

    Description: 
It would be useful to have a marker interface like the following in the Jackrabbit API:

    interface NonExternalEventListener extends EventListener { }

The observation dispatcher could then avoid delivering any external events to that listener.

For backwards compatibility such a listener should still use an "if (!event.isExternal()) { ... }" wrapper for event processing. That way the listener can avoid processing external events also when registered with an older repository that doesn't know about this marker interface.
