What would be the Datanucleus/JDO implementation to this:
Suppose I have a POJO, `Hub` which represents a place/location:
```java
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:
```java
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?
