org.apache.ojb.broker.core.proxy.CollectionProxy
Interface which Collection proxies need to implement to be treated like collection proxies in ODMG.
Presently the collection proxy impl class can be plugged in and not implement this interface, but those implementations will *not* be treated as proxies by OJB
