+# Subscribing to State Changes of a Remote Object
 
-IPC/RPC allows you to subscribe to the state changes of a remote stub object. When the remote stub object dies, a death notification will be sent to your local proxy object. You can also unsubscribe from the state changes if they are no longer needed. Such subscription and unsubscription are controlled by APIs. To be specific, you need to implement the  **IRemoteObject.DeathRecipient**  interface and the  **onRemoteDied**  method to clear resources. This callback is invoked when the process accommodating the remote stub object dies, or the device accommodating the remote stub object leaves the network. It is worth noting that these APIs should be called in the following order: The proxy object must first subscribe to death notifications of the stub object. If the stub object is in the normal state, the proxy object can cancel the subscription as required. If the process of the stub object exits or the device hosting the stub object goes offline, subsequent operations customized by the proxy object will be automatically triggered.

-You can use WebSocket to establish a bidirectional connection between a server and a client. Before doing this, you need to use the **createWebSocket** API to create a **WebSocket** object and then use the **connect** API to connect to the server.

+The **screenlock** module is a system module in OpenHarmony. It provides APIs for screen lock applications to subscribe to screen lock status changes as well as callbacks for them to receive the results. It also provides APIs for third-party applications to unlock the screen, obtain the screen locked status, and check whether a lock screen password has been set.
