there is a new cache type called AttributeBasedObjectCacheImpl (as
ObjectCachePerClassImpl was already used).
you can choose a per-class cache by using the attribute name="cacheClass" value =
"some class name" in your class descriptor
like this:
<class-descriptor
class="org.apache.ojb.broker.Article"
proxy="dynamic"
table="Artikel"
>
<attribute attribute-name="cacheClass"
attribute-value="org.apache.ojb.broker.cache.ObjectCacheUnlimitedImpl" />
btw Thomas, how do you want docs for there features?

hmm, good question! Seems you need to cast to this implementation
(really bad) and use
public void setClassCache(Class objectClass, ObjectCache cache)
e.g.
cache = broker.serviceObjectCache();
((Meta....)cache).setClassCache(myClass, new
ObjectCacheDefaultImpl(null));
but there is no method to check if the cache already contains
'myClass' as key, thus it can be possible possible that I override
again and again.

think this is a good idea to make this implementation
really useful. Are you willing to improve this implementation?
