Subject New Monitor framework
Date Wed, 15 Aug 2001 15:33:29 GMT
I added a new package in Excalibur that will be used for
monitoring resources.  There will be two monitors: passive
and active.  The passive monitor will rely on the Resources
themselves to keep up to synch.  This is not that exciting,
but easy to write.  The second is an Active Monitor.  The
Active Monitor will issue one or more threads to examine
the group of resources based on the policies used.  When
a Resource has changed, it will propogate that change to
all PropertyChangeListeners examining the resource.

This opens up a whole new realm to the Caching implementation,
which can confidently serve old content until it is told there
is new information.  In fact, it can continue to serve the older
content until the new information is loaded into the cache.

All this comming soon.
