![]() The Realm Expo template uses: Expo, a framework to develop, build and deploy React Native applications quickly. This documentation covers how to initialize and work with the Realm Expo template. IndexOutOfBoundsException - if location size(). The Realm Expo template provides a fully working React Native application that you can use to bootstrap your app development project with Realm. IllegalStateException - if Realm instance has been closed or container object has been removed. In that case the object will transparently be copied to Realm using pyToRealm(RealmModel, ImportFlag.) or pyToRealmOrUpdate(RealmModel, ImportFlag.) if it has a primary key. Managed RealmLists: It is possible to add unmanaged objects to a RealmList that is already managed. If adding managed objects to an unmanaged RealmList they will not be copied to the Realm again if using pyToRealm(RealmModel, ImportFlag.) afterwards. Unmanaged RealmLists: It is possible to add both managed and unmanaged objects. If the location is equal to the size of this List, the object is added at the end. Query, modify, delete, and more all from one interface. The object is inserted before any previous element at the specified location. Explore and interact with your data using Compass, the GUI for MongoDB. Inserts the specified object into this List at the specified location. In that case, you can access only first Integer.MAX_VALUE elements in it. RealmList can contain more elements than Integer.MAX_VALUE. Unmanaged elements in this list can be added to a Realm using the pyToRealm(Iterable, ImportFlag.) method. This is useful when dealing with JSON deserializers like GSON or other frameworks that inject values into a class. When Realm cancels a write transaction (as when an operation in the transaction causes an error), all changes are discarded (or 'rolled back'). For synced realms, the SDK queues the change for synchronization with Atlas App Services. Unmanaged RealmLists can be created by the user and can contain both managed and unmanaged RealmObjects. When Realm commits a transaction, Realm writes all changes to disk. Managed RealmLists will automatically update the content whenever the underlying Realm is updated, and can only be accessed using the getter of a io.realm.RealmObject. Only Realm can create managed RealmLists. In managed mode all objects are persisted inside a Realm, in unmanaged mode it works as a normal ArrayList. ![]() RealmList has two modes: A managed and unmanaged mode. RealmList is used to model one-to-many relationships in a io.realm.RealmObject.
