Andy Jefferson commented on JDO-652:
------------------------------------
@Matthew, you open Eclipse (and set it up to have the annotation processor
enabled). You write a model class ("Person"). When pressing "Save" Eclipse will
attempt to compile it. Prior to compilation all files to be compiled that have
the required annotations (@PersistenceCapable) are passed to the annotation
processor(s). The annotation processor generates the equivalent query source
code (QPerson). The compiler then compiles all classes (model + query).
When compilation has finished the user starts to write a persistence class.
They can reference Person and QPerson since both are compiled classes.

> 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.
