public static class ExpressionStoreQuery.DataStoreExecutor
The DataStoreExecutor executes the query against the
implementation's overridden executeQuery(org.apache.openjpa.kernel.StoreQuery, java.lang.Object[], org.apache.openjpa.kernel.StoreQuery.Range)
method.

Extract the value of the orderIndex th ordering
expression in Query#getOrderingClauses from the
given result object. |

This method is used when several result lists have to be merged
in memory. If this exeuctor's parent query supports executors on
abstract or interface classes, this method will not be used.
