+1 for event handling.  
+1 For similar changes in Torque so that a JCS event handling mechanism
calls into org.apache.torque.manager.CacheListener.  In particular, I want
the remote and Lateral caching updates/removes to hook into Torque.

Subject: Alter behavior through event handling?


I have not been able to determine if this is possible, but here is what I am
trying to do.

app 1) When something runs its life in the cache, rather then drop from the
cache entirely, call a method on that particular object to refresh its data

app 2) When something runs its life in the cache, drop it from the cache,
and since the item being cached is a java.io.File reference delete the file
from the hard drive  (no, I cannot simple cache the java.io.File contents in
JCS they aren't truly serializable and need to be streamed/loaded manually
to disk)

I envision achieving this behavior by intercepting a cache release event of
sorts, but I cannot figure out how to latch on to the event handler to
process it.  Am I missing something?  Or are the events and event handlers
not supposed to be fooled around with?
