QueryHints.RESULT_TYPE, ResultType.Map

by Montechristos posted Aug 7 2014, 9:18

Hi James,

I saw an old post of yours about EclipseLink and how to hint it to return a map.

Now I am trying to use that in Netbeans8, but I cannot find the classes QueryHints and ResultType. Do I need a specific version of EclipseLink?

Many thanks,
Montechristos

Hi Montechristos,

QueryHints and ResultType are in the org.eclipse.persistence.config package.

https://www.eclipse.org/eclipselink/api/2.4/org/eclipse/persistence/config/QueryHints.html#RESULT_TYPE

https://www.eclipse.org/eclipselink/api/2.4/org/eclipse/persistence/config/ResultType.html

The hints are just strings so,

query.setHint("eclipselink.result-type", "Map");


will work as well.
