Class RealmSchema

Describes the complete set of classes which may be stored in a Realm, either from assembly declarations or, dynamically, by evaluating a Realm from disk. To construct a new RealmSchema instance, use the RealmSchema.Builder API.
By default this will be all the IRealmObjects, IEmbeddedObjects and IAsymmetricObjects in all your assemblies. Unless you restrict with Schema. Just because a given class may be stored in a Realm doesn't imply much overhead. There will be a small amount of metadata but objects only start to take up space once written.
