[osgi-dev] track trackers?
I believe the answer is no... but Is it possible to list out all the trackers in the registry? Particularly, given a type, is it possible to find who might be interested in it? I'm thinking along the lines of a DTO which might report this info. The goal is to observe as a developer the possible interested parties for a given type. -- *Raymond Augé* http://www.liferay.com/web/raymond.auge/profile (@rotty3000) Senior Software Architect *Liferay, Inc.* http://www.liferay.com (@Liferay) ___ OSGi Developer Mail List osgi-dev@mail.osgi.org https://mail.osgi.org/mailman/listinfo/osgi-dev
Re: [osgi-dev] track trackers?
You cannot see trackers in the registry since the direction is wrong. ServiceTrackers are a layer above the registry and use ServiceListeners to follow services. So you could use ListenerHooks [1] to see what services bundles are listening for. Also FYI, UnfilteredServiceListener [2] was added in Core R5 to allow certain users to advertise their service interest via ListenerHooks while remaining unfiltered.
