How to do range query with Datanucleus/JDO?

Question

What would be the Datanucleus/JDO implementation to this:

Suppose I have a POJO, Hub which represents a place/location:

class Hub {
    List<Schedule> schedules; 
}

And a Schedule class to represent a specific day schedule of opening and closing of that place:

class Schedule {
    String day;
    LocalTime opens;
    LocalTime closes;
}

And then a query to those Hubs to find which opens and closes during a specific day, say, query with this constraint:

new Schedule().builder()
    .day("Monday")
    .opens(LocalTime.parse("09:00")
    .close(LocalTime.parse("17:00").build();

Note that LocalTime is not Date

So in this case we want to query for Hubs that are open on Mondays at 9am to 5pm.

1. What would be the Datanucleus/JDO implementation for the Hub?
2. What would be the query implementation to achieve the desired result as described?
