ohos.data.search.model.ChangedIndexContent

public class ChangedIndexContent
extends Object

A wrapper class of changed indexes.

This class wraps indexes that are inserted, updated, and deleted in the index library. If the client has registered a listener for index changes, callbacks will be invoked to send notifications to the client when an index change occurs. You can call ChangedIndexContent#getInsertedItems(), ChangedIndexContent#getUpdatedItems(), and ChangedIndexContent#getDeletedItems() to obtain the inserted, updated, and deleted indexes. The returned list, if not empty, contains the changed indexes.
