Craig L Russell commented on JDO-652:
-------------------------------------
I very much like the current builder methods in ifThenElse patch.
The builders that take literals and not class<V> are very user-friendly.
And I agree that the builder taking only class<V> is not needed.
And I like the names of the builders ifThen and elseEnd.
Side question: what is the meaning of niladic sum() exp() and avg() applied to
NumericExpression?

> 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
