implementations of ObjectCache

Hi. I am exploring the implementations of ObjectCache.
Where can I find documents about ObjectCacheJCSImpl,
ObjectCachePerClassImpl, ObjectCacheUnlimitedImpl, etc.?

In the javadoc I do not find enough information....

Thanks,
Marcello Zaniboni

Thanks :-)
By the way... I am having problems with threads: it seems that multiple
threads accessing the same set of records see them differently. Indeed all
the threads but one get records in which some fields/references are null,
but in the DB these columns are valorized.
I thought that it was because the ObjectCacheDefaultImpl uses a HashMap, not
a Hashtable; that's why I am searching alternative implementations. At the
moment I cannot see any cache implementation that satisfies this
requirement... I am wrong?
Thanks again.
Regards,
Marcello

Try latest from CVS to get the refactored version
of cache package (with little more javadoc). Have a
look in the sources.

Promise to improve documentation of caching
package till 1.1 (maybe 1.0)
