/**
 * Creates a Realm object for each object in a JSON array. This must be done within a transaction.
 * JSON properties with unknown properties will be ignored. If a {@link RealmObject} field is not present in the
 * JSON object the {@link RealmObject} field will be set to the default value for that type.
 * <p>
 * This API is only available in API level 11 or later.
 *
 * <p>
 * This method currently does not support value list field.
 *
 * @param clazz type of Realm objects created.
 * @param inputStream the JSON array as a InputStream. All objects in the array must be of the specified class.
 * @throws RealmException if mapping from JSON fails.
 * @throws IllegalArgumentException if the JSON object doesn't have a primary key property but the corresponding
 * {@link RealmObjectSchema} has a {@link io.realm.annotations.PrimaryKey} defined.
 * @throws IOException if something was wrong with the input stream.
