Andy Jefferson commented on JDO-749:
------------------------------------
The XXXExpression classes could be included in the JDO API, but with the
proviso that the JDO API would need to be built using JDK 1.8 (though runnable
for JRE 1.7+).
> Support for java.time types, and querying using associated methods
> ------------------------------------------------------------------
>
> Key: JDO-749
> URL: https://issues.apache.org/jira/browse/JDO-749
> Project: JDO
> Issue Type: New Feature
> Components: api, specification, tck
> Reporter: Andy Jefferson
>
> Refer to an associated issue for JPA for what support should look like
> https://java.net/jira/browse/JPA_SPEC-63
> The methods that should be supported in queries would initially be
> LocalDateTime : getDayOfMonth, getMonth, getYear, getHour, getMinute,
> getSecond
> LocalTime : getHour, getMinute, getSecond
> LocalDate : getDayOfMonth, getMonth, getYear
> These would need to be part of JDOQL string-based, as well as the
> JDOQLTypedQuery (hence have equivalent Expression classes).
> Note that all of these are already implemented in DataNucleus, and there are
> JDOQLTypedQuery expression classes available.
> Timing of this simply depends on the JRE that the next release of JDO is
> targetted at, since this needs Java 8.
