Realm delete all except one table

Question

This is Realm Java so I'm doing

realm.beginTransaction();
realm.deleteAll();
realm.commitTransaction();

I have 20 or so Realm classes. I only want to keep one.

Instead of doing

realm.beginTransaction();
  realm.delete(Table1.class);
  realm.delete(Table2.class);
  realm.delete(Table3.class);
  ...
realm.commitTransaction();

Is there a way to delete all tables except one?

"deleteAll.except(Table12.class)" etc?

thanks!

Sure!

final RealmConfiguration realmConfiguration = realm.getConfiguration();
r.executeTransaction((realm) -> {
    for(Class<? extends RealmModel> clazz : realmConfiguration.getRealmObjectClasses()) {
        if(clazz != Table12.class) {
            realm.delete(clazz);
        }
    }
});
