   Each HAP of the Entry or Feature type has an AbilityStage class instance during the runtime. When the code in the HAP is loaded to the process for the first time, the system creates an AbilityStage class instance first. Each UIAbility class defined in the HAP is associated with this class instance after instantiation. Through this class instance, you can obtain the runtime information of the UIAbility instances in the HAP.

 ## Restrictions on Data Type Declarations of State Variables
 
-The data type declaration of the **@State**, **@Provide**, **@Link**, or **@Consume** decorated state variables can consist of only one of the primitive data types or reference data types.
-
-Example:
-
-```ts
-// xxx.ets
-@Entry
-@Component
-struct IndexPage {
-  // Incorrect: @State message: string | Resource = 'Hello World'
-  @State message: string = 'Hello World'

-        Text(`${this.message}`)
-          .fontSize(50)
-          .fontWeight(FontWeight.Bold)
+1. The data types of state variables decorated by state decorators must be explicitly declared. They cannot be declared as **any** or **Date**.
+
+    Example:
+
+    ```ts
+    // xxx.ets
+    @Entry
+    @Component
+    struct DatePickerExample {
+      // Incorrect: @State isLunar: any = false

+2. The data type declaration of the **@State**, **@Provide**, **@Link**, or **@Consume** decorated state variables can consist of only one of the primitive data types or reference data types.
+
+    The **Length**, **ResourceStr**, and **ResourceColor** types are combinations of primitive data types or reference data types. Therefore, they cannot be used by the aforementioned types of state variables.
+    For details about the definitions of **Length**, **ResourceStr**, and **ResourceColor**, see [Types](../../application-dev/reference/arkui-ts/ts-types.md).

 - **@LocalStorageProp**: establishes one-way data binding between a component and the **LocalStorage**. Specifically, this is achieved by decorating the component's state variable with **@LocalStorageProp(*key*)**. Wherein, **key** is the attribute key value in the **LocalStorage**.
 - **PersistentStorage**: provides a set of static methods for managing persistent data of applications. Persistent data with specific tags can be linked to the **AppStorage**, and then the persistent data can be accessed through the **AppStorage** APIs. Alternatively, the **@StorageLink** decorator can be used to access the variable that matches the specific key.
 - **Environment**: provides the **AppStorage** with an array of environment state attributes that are required by the application and describe the device environment where the application runs. It is a singleton object created by the framework when the application is started.

+# @ohos.file.hash (File Hash Processing)
+
+The **fileHash** module implements hash processing on files.
+
+> **NOTE**
+>
+> - The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+> - The APIs of this module support processing of error codes. For details, see [File Management Error Codes](../errorcodes/errorcode-filemanagement.md).
+
+## Modules to Import
+
+```js
+import Hash from '@ohos.file.hash';
+```
+
+## Guidelines
+
+Before using the APIs provided by this module to perform operations on a file or directory, obtain the path of the file or directory in the application sandbox as follows:
+
+**Stage Model**
+
+ ```js
+import UIAbility from '@ohos.app.ability.UIAbility';
+
+export default class EntryAbility extends UIAbility {
+    onWindowStageCreate(windowStage) {
+        let context = this.context;
+        let pathDir = context.filesDir;
+    }
+}
+ ```
+
+**FA Model**
+
+ ```js
+ import featureAbility from '@ohos.ability.featureAbility';
+ 
+ let context = featureAbility.getContext();
+ context.getFilesDir().then((data) => {
+      let pathDir = data;
+ })
+ ```
+
+For details about how to obtain the FA model context, see [Context](js-apis-inner-app-context.md#context).
+
+## Hash.hash
+
+hash(path: string, algorithm: string): Promise<string>
+
+Calculates a hash value for a file. This API uses a promise to return the result.
+
+**System capability**: SystemCapability.FileManagement.File.FileIO
+
+**Parameters**
+
+| Name   | Type  | Mandatory| Description                                                        |

+# @ohos.file.securityLabel (Data Label)
+
+The **securityLabel** module provides APIs for managing data security levels of files, including obtaining and setting file security levels.
+
+> **NOTE**
+>
+> - The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+>- The APIs of this module support processing of error codes. For details, see [File Management Error Codes](../errorcodes/errorcode-filemanagement.md).
+
+## Modules to Import
+
+```js
+import securityLabel from '@ohos.file.securityLabel';
+```
+
+## Guidelines
+
+Before using the APIs provided by this module to perform operations on files or directories, obtain the path of the file or directory in the application sandbox as follows:
+
+**Stage Model**
+
+ ```js
+import UIAbility from '@ohos.app.ability.UIAbility';
+
+export default class EntryAbility extends UIAbility {
+    onWindowStageCreate(windowStage) {
+        let context = this.context;
+        let pathDir = context.filesDir;
+    }
+}
+ ```
+
+**FA Model**
+
+ ```js
+ import featureAbility from '@ohos.ability.featureAbility';
+ 
+ let context = featureAbility.getContext();
+ context.getFilesDir().then((data) => {
+      let pathDir = data;
+ })
+ ```
+
+For details about how to obtain the FA model context, see [Context](js-apis-inner-app-context.md#context).

+An event is a communication mechanism used to synchronize tasks. Events have the following features:
 
 - Events can be synchronized in one-to-many or many-to-many mode. In one-to-many mode, a task can wait for multiple events. In many-to-many mode, multiple tasks can wait for multiple events. However, a write event wakes up only one task from the block.

 ### Working Principles
 
-**Initializing an event**: An event control block is created to maintain a collection of processed events and a linked list of tasks waiting for specific events.

-**Writing an event**: When a specified event is written to the event control block, the event control block updates the event set, traverses the task linked list, and determines whether to wake up related task based on the task conditions.
+An event control block is created to maintain a set of processed events and a linked list of tasks waiting for specific events.
 
-**Reading an event**: If the read event already exists, it is returned synchronously. In other cases, the return time is determined based on the timeout period and event triggering status. If the wait event condition is met before the timeout period expires, the blocked task will be directly woken up. Otherwise, the blocked task will be woken up only after the timeout period has expired.
+**Writing an Event** 
 
-The input parameters **eventMask** and **mode** determine whether the condition for reading an event is met. **eventMask** indicates the mask of the event. **mode** indicates the handling mode, which can be any of the following:
+When an event is written to the event control block, the event control block updates the event set, traverses the task linked list, and determines whether to wake up related tasks based on the task conditions.
 
-- **LOS_WAITMODE_AND**: Event reading is successful only when all the events corresponding to **eventMask** occur. Otherwise, the task will be blocked, or an error code will be returned.
+**Reading an Event** 
 
-- **LOS_WAITMODE_OR**: Event reading is successful when any of the events corresponding to **eventMask** occur. Otherwise, the task will be blocked, or an error code will be returned.
+If the event to read already exists, it is returned synchronously. In other cases, the event is returned based on the timeout period and event triggering conditions. If the wait condition is met before the timeout period expires, the blocked task will be directly woken up. Otherwise, the blocked task will be woken up only after the timeout period has expired.
+
+The parameters **eventMask** and **mode** determine whether the condition for reading an event is met. **eventMask** specifies the event mask. **mode** specifies the handling mode, which can be any of the following:
+
+- **LOS_WAITMODE_AND**: Read the event only when all the events corresponding to **eventMask** occur. Otherwise, the task will be blocked, or an error code will be returned.
+
+- **LOS_WAITMODE_OR**: Read the event only when any of the events corresponding to **eventMask** occur. Otherwise, the task will be blocked, or an error code will be returned.
 
 - **LOS_WAITMODE_CLR**: This mode must be used with one or all of the event modes (LOS_WAITMODE_AND | LOS_WAITMODE_CLR or LOS_WAITMODE_OR | LOS_WAITMODE_CLR). In this mode, if all event modes or any event mode is successful, the corresponding event type bit in the event control block will be automatically cleared.
 
-**Clearing events**: Clear the event set of the event control block based on the specified mask. If the mask is **0**, the event set will be cleared. If the mask is **0xffff**, no event will be cleared, and the event set remains unchanged.
+**Clearing Events**
+
+The events in the event set of the event control block can be cleared based on the specified mask. The mask **0** means to clear the event set; the mask **0xffff** means the opposite.

+**Destroying Events** 
 
-**Destroying an event**: Destroy the specified event control block.
