Iterating
Hi,
I'm using JCS to replace my current cache system for a webapp, and I
need to be able to iterate through at least one region of the cache in
order to mimic the ServletContext's functionality. Is this possible?
I've been searching the mailing list archives and the API docs and
haven't found anything.
If this isn't possible, is there a good way to do this? I was thinking
I'd just put an ArrayList in the cache with all the keys to the cached
elements in it.
Thanks!

I'm currently implementing a getMatching( String pattern ) API. Perhaps this will meet your needs.
I might be able to implement a getKeys() method as well, but it will have some odd edge cases.

[I know the original question was posted more than a year ago, but in case
anyone else is perusing these archives for a similar issue...]
I faced a similar requirement, but more so required an ordered iteration
over the elements/keys. We are supporting this by using an in-memory index
of all the keys (ArrayList to the rescue). Although this results in some
degree of redundancy, it provides a flexible interface for when having to
deal only with keys (or their indexes, such as getting the size of the
cache) without having to deal with the cache itself.

I tried this myself but had problems as I have a clustered cache using
the lateral cache auxillary, and the lateral cache doesn't support
groups.

Hi,
JCS supports the concept of groups within a region, it is able to
retrieve a Set of the keys of cached objects belonging to a group for
example. (The user manual does not say too much about this functionality
but you could check out the API of
org.apache.jcs.access.GroupCacheAccess.) One solution could be to put
every object you need to iterate through within the same group.
Hope this helps,
Zsolt
