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

org.apache.openjpa.lib.rop.MergedResultObjectProvider
A result object provider that merges multiple result object provider delegates. Support exists for maintaining ordering of the internally held results, provided that each of the individual results is itself ordered. @author Abe White @author Marc Prud'hommeaux
