Examples of org.apache.openjpa.lib.rop.SimpleResultList

org.apache.openjpa.lib.rop.SimpleResultList
An almost stateless {@link ResultList} designed for use with resultobject providers backed by efficient random-access data structures, such as the {@link ListResultObjectProvider}. This result list does not perform any caching. @author Abe White @nojavadoc
