    Description

      There are various querying capabilities of this type around. JPA2 has its Criteria query API. Third party solutions like QueryDSL also exist, in its case providing a JDOQL implementation (as well as JPQL, and HQL). We should seriously consider introducing something along these lines in the JDO2.4 timeframe.

      There is a comparison of JPA Criteria with QueryDSL over at
