Package edu.berkeley.guir.lib.satin.watch Description

An implementation of the Observer pattern. Used to keep the state in Satin consistent. Watchable objects can be observed by Watcher objects. Watcher objects are sent notifications by Watchable objects when "interesting" things happen, in order to keep the state of the system consistent and correct.

This class is for internal use in SATIN and DENIM only. We're going to be switching to the JavaBeans notification model by the next release.
