java Collections




Hello,

I'm considering using ozone for a project (just started looking at it), but looking
through the API documentation, I find no implementations of java.util.Map,
java.util.SortedMap, java.util.Set, java.util.SortedSet, which I need.  I found a
few implementations of other java collections in package org.ozoneDB.odmg.  I need
these collections to contain thousands or perhaps millions of objects, so keeping
the entire collection in memory at once (such as the standard java implementations
do) will not work.  Any suggestions?

I am not so much interested in a database which allows inserts and queries by
identity, but rather a database which consists of (a potentially quite large graph
of) persistent objects, which may be accessed by "reachability" of member methods
and fields.  Quoting from the ozone site, "The main goal of ozone is to add
persistence and transactions to the Java object model in a transparent manner.
ozone applications should look and work like ordinary Java applications."  That
would be quite nice.

Thanks,

Jim Newsham
