[jira] Updated: (FELIX-1804) Consider adding an Interceptor API

     [ https://issues.apache.org/jira/browse/FELIX-1804?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Thomas Diesler updated FELIX-1804:
----------------------------------

    Description: 
Please consider adding a bundle state change interceptor API. For more background on this, please have a look at

http://jbossosgi.blogspot.com/2009/10/extender-pattern-vs-lifecycle.html 

A possible API could look like this

    void setBundleStateAndNotify(BundleImpl bundle, int state)
    {
        synchronized (m_bundleLock)
        {
           if (interceptor != null)
              interceptor.processStateChange(bundle, state);

            bundle.__setState(state);
            m_bundleLock.notifyAll();
        }
    }

    interface BundleStateInterceptor()
    {
       void processStateChange(Bundle bundle, int state);   
    }
