List<Object> Or RealmList<RealmObject> on Realm Android
26,572
Christian from Realm here. You can only save objects that extend RealmObject inside a Realm. This is because Realm is not a schemaless database. We do require a schema and that schema is defined by your objects that extend RealmObject. We use RealmList because it abstracts away the communication with the underlying core database, but it implements the List interface.
This means that
public class Foo extends RealmObject {
private List<Object> objects; // not legal
private RealmList<Object> objects; // not legal
private RealmList<RealmObject> objects; // not legal
}
public class Foo extends RealmObject {
private RealmList<Foo> objects; // legal
}
List<Foo> reference = foo.getObjects(); // Legal

I need a
list<Object>
using Realm. I triedRealmList<RealmObject>
but it doesn't work becauseRealmObject
is abstract.
