Realm's model can finally not inherit Realmobject __realmmodel

The old implementation can only be inherited realmobject this abstract class, for some Third-party class libraries, if the same need to inherit some of the base classes, there is likely to be a conflict:

public class User extends Realmobject {
    ...
}

Therefore, starting with version 0.89.0, you can implement a Realmmodel interface directly and precede the class declaration with a @realmclass annotation declaration:

@RealmClass public
class User implements Realmmodel {
    ...
}

Then the method invoked on the Realmobject object can only be invoked in the form of a static method:

With Realmobject
User.deletefromrealm ();
User.isvalid ();
User.addchangelistener (listener);

With Realmmodel
realmobject.deletefromrealm (user);
Realmobject.isvalid (user);
Realmobject.addchangelistener (user, listener);
