Inheritance / Polymorphism #761
Description
A highly request feature is polymorphism. Mostly for use in ListAdapters, but a lot of other scenarios exists.
We need support for the following:
- Abstract RealmObject classes
- Query support
Example
public abstract Animal extends RealmObject {
private String name;
}
public class Dog extends Animal {
private boolean willPlayCatch;
}
public class Spider extends Animal {
private boolean isScary;
}
// Following should be possible
RealmResults<Animal> animals = realm.where(Animal.class).equalsTo("name","Foo").findAll();
String name = animals.get(0).getName();
RealmResults<Dog> dogs = realm.where(Dog.class).equalsTo("name","Foo").and().equalsTo("willPlayCatch", true).findAll();
String name = dogs.get(0).getName();
