Example 1 with RealmObjectSchema

use of io.realm.RealmObjectSchema in project realm-java by realm.

the class Migration method migrate.

    // with the same object creation and query capabilities.
    // A DynamicRealm uses Strings instead of Class references because the Classes might not even exist or have been
    // renamed.
    // Access the Realm schema in order to create, modify or delete classes and their fields.
    RealmSchema schema = realm.getSchema();
