+## @BuilderParam<sup>8+<sup>
+The **@BuilderParam** decorator is used to modify the function type attributes (for example, `@BuilderParam content: () => any;`) in a custom component. When the custom component is initialized, the attributes modified by the **@BuilderParam** decorator must be assigned values.
 
 ### Background
 
-In certain circumstances, you may need to add a specific function, such as a click-to-jump action, to a custom component. However, embedding an event method directly inside of the component can add the function to all places where the component is initialized. This is where the @BuilderParam decorator come into the picture. When initializing a custom component, you can assign a @Builder decorated method to the @BuilderParam decorated attribute, thereby adding the specific function to the custom component.

+When initializing a custom component through parameters, assign a **@Builder** decorated method to the **@BuilderParam** decorated attribute — **content**, and call the value of **content** in the custom component. If no parameter is passed when assigning a value to the **@BuilderParam** decorated attribute (for example, `content: this.specificParam`), define the type of the attribute as a function without a return value (for example, `@BuilderParam content: () => void`). If any parameter is passed when assigning a value to the **@BuilderParam** decorated attribute (for example, `callContent: this.specificParam1("111")`), define the type of the attribute as `any` (for example,`@BuilderParam callContent: any;`).

 ### Component Initialization Through Trailing Closure
+In a custom component, use the **@BuilderParam** decorated attribute to receive a trailing closure. When the custom component is initialized, the component name is followed by a pair of braces ({}) to form a trailing closure (`CustomComponent(){}`). You can consider a trailing closure as a container and add content to it. For example, you can add a component (`{Column(){Text("content")}`) to a trailing closure. The syntax of the closure is the same as that of [build](../ui/ts-function-build.md). In this scenario, the custom component has one and only one **@BuilderParam** decorated attribute.

-
-Example: Add a &lt;Column> component and a click event to the closure, and call the specificParam method decorated by @Builder in the new &lt;Column&gt; component. After the &lt;Column&gt; component is clicked, the value of the component's header attribute will be changed to changeHeader. In addition, when the component is initialized, the content of the trailing closure will be assigned to the closer attribute decorated by @BuilderParam.

+In this section, we will develop an infographic food details page, by building custom components through the container components **\<Stack>** and **\<Flex>** as well as basic components **\<Image>** and **\<Text>**.
 
 
 ## Building the Stack Layout
 
 1. Create a food name.
-     Delete the code of the build method in the project template, create a &lt;Stack&gt; component, and place the &lt;Text&gt; component in the braces of the &lt;Stack&gt; component so that the &lt;Text&gt; component becomes a child component of the &lt;Stack&gt; component. A &lt;Stack&gt; component consists of one or more child components. The latter child component overwrites the former one.

 2. Display food pictures.
-     Create an &lt;Image&gt; component and specify a URL for it. The &lt;Image&gt; and &lt;Text&gt; components are mandatory. To display the &lt;Text&gt; component above the &lt;Image&gt; component, you need to declare the &lt;Image&gt; component first. Image resources are stored in the rawfile folder in resources. When referencing the resources in the rawfile folder, use the `"$rawfile('filename')"`  format, where filename indicates the relative path of the file in the rawfile folder. Currently, `$rawfile` only allows the &lt;Image&gt; component to reference image resources.

 ### Function
 
-Personal Identification Number (PIN) authentication provides user authentication capabilities and applies to identity authentication scenarios, such as device unlocking, payment, and app logins. After a user registers a PIN, the PIN authentication (pin_auth) module unlocks the device only when a correct PIN is entered. The figure below shows the architecture of PIN authentication.

After a user registers a PIN, the PIN authentication (pin_auth) module unlocks the device only when a correct PIN is entered. The figure below shows the architecture of PIN authentication.
 
-The pin_auth driver is developed based on the Hardware Driver Foundation (HDF). The pin_auth driver model shields hardware differences and provides stable PIN authentication capabilities for the user IAM framework(UserIAM) and PIN authentication system ability (SA). The PIN authentication capabilities include obtaining the PIN authentication executor list, executor information, anti-brute force information of the specified template, comparing the template list of the executor and that of UserIAM, enrolling or deleting PINs, and performing PIN authentication.

 Dynamic memory management allows memory blocks of any size to be allocated from a large contiguous memory \(memory pool or heap memory\) configured in the system based on user demands when memory resources are sufficient. The memory block can be released for further use when not required. Compared with static memory management, dynamic memory management allows memory allocation on demand but causes fragmentation of memory.

 For example, insert 40-byte free memory to a free list. The 40-byte free memory corresponds to the 10th free list in the range of \[40, 43\], and the 10th bit indicates the use of the free list. The system inserts the 40-byte free memory to the 10th free list and determines whether to update the bitmap flag. When 40-byte memory is requested, the system obtains the free list corresponding to the memory block of the requested size based on the bitmap flag, and then obtains a free memory node from the free list. If the size of the allocated node is greater than the memory requested, the system splits the node and inserts the remaining node to the free list. If 580-byte free memory needs to be inserted to a free list, the 580-byte free memory corresponds to the 47th \(31 + 2 x 8\) free list in L2 range \[2^9, 2^9+2^6\], and the 47th bit indicates the use of the free list. The system inserts the 580-byte free memory to the 47th free list and determines whether to update the bitmap flag. When 580-byte memory is requested, the system obtains the free list corresponding to the memory block of the requested size based on the bitmap flag, and then obtains a free memory node from the free list. If the size of the allocated node is greater than the memory requested, the system splits the node and inserts the remaining node to the free list. If the corresponding free list is empty, the system checks for a free list meeting the requirements in a larger memory range. In actual application, the system can locate the free list that meets the requirements at a time.

 The OpenHarmony LiteOS-M kernel is a lightweight operating system \(OS\) kernel designed for the IoT field. It features small size, low power consumption, and high performance. The LiteOS-M kernel has simple code structure, including the minimum function set, kernel abstraction layer \(KAL\), optional components, and project directory. It supports the Hardware Driver Foundation \(HDF\), which provides unified driver standards and access mode for device vendors to simplify porting of drivers and allow one-time development for multi-device deployment.
 
-The OpenHarmony LiteOS-M kernel architecture consists of the hardware layer and hardware-irrelevant layers, as shown in  [Figure 1](#fig1287712172318). The hardware layer is classified based on the compiler toolchain and chip architecture, and provides a unified Hardware Abstraction Layer \(HAL\) interface to improve hardware adaptation and facilitate the expansion of various types of AIoT hardware and compilation toolchains. The other modules are irrelevant to the hardware. The basic kernel module provides basic kernel capabilities. The extended modules provide capabilities of components, such as the network and file systems, as well as exception handling and debug tools. The KAL provides unified standard APIs.

+
+## 完整
+
+【规则】避免任务场景缺失。开始写作前，应通过用户与任务分析活动，明确文档要提供哪些任务场景的指导信息。
+
+【规则】通过写作模板来保证内容的完整性：
+
+- OpenHarmony文档遵从结构化、模块化理念，对于每类信息，均根据用户的信息需求提供相应内容模板，即“[OpenHarmony文档写作模板](https://gitee.com/openharmony/docs/tree/master/zh-cn/contribute/template)”。请从中选择最贴近待写作内容的模板，保证知识点覆盖完整。
+
+- 写作模板中“必选”的节点，禁止删除。
+
+- 写作模板中“可选”的节点，在确定不涉及的情况下，删除即可。
+
+
+## 具体
+
+【规则】用具体的描述代替抽象/晦涩的描述。
+
+| **正例** | 反例 |
+| -------- | -------- |
+| 在编译构建过程中，提示LABEL_VALUE_ERROR错误信息。 | 编译构建失败。 |
+
+【规则】表示数量或程度时，避免用笼统的“多”“少”“大”，改为具体的、易于感知或衡量的数字。
+
+| **正例** | 反例 |
+| -------- | -------- |
+| 文件大于16MB | 文件超限 |
+| 等待30分钟左右 | 等待较长的时间 |
+| CPU运行速度提升80% | 性能增强 |
+
+
+## 简洁
+
+【规则】使用主谓结构、主谓宾结构的句子，避免添加不必要的修饰成分。
+
+【规则】避免使用长连句。同一句子中的逗号数不能超过5个。
+
+【规则】禁止使用双重否定。
+
+【规则】言简意赅，直接陈述观点。避免无意义的词语，包括表示程度、语气的词。
+
+| **正例** | 反例 |
+| -------- | -------- |
+| 属性不允许重复定义。 | 每个属性最多只允许出现一次。 |
+| 绑定服务与通知。 | 将服务与通知绑定就好了。 |
+
+【规则】根据用户的技能水平，剔除不必要的信息。
+
+
+## 清晰
+
+【规则】确保语言描述清晰，不模糊，不晦涩，易理解（传递一个清楚的意思）：
+
+- 遵循“[具体](#具体)”、“[简洁](#简洁)”的要求。
+
+- 确保每个代词都有清晰的指代，能够通过上下文清晰获取其指代对象，便于理解与翻译。
+
+- 参数取值原则、原理描述清晰易懂。
+    | **正例** | 反例 |
+  | -------- | -------- |
+  | 当参数A设置为1时：<br/>-&nbsp;如果参数B设置为1，表示有下一级跳转，此时页签为方形9宫格。<br/>-&nbsp;如果参数B设置为0，表示无下一级跳转，此时页签自动变为圆形9宫格。 | 在参数A为1同时参数B为1，如有下一级跳转则页签为方形9宫格，若无下一级跳转则界面页签会自动变为圆形9宫格。 |
+
+- 避免使用引起歧义的词。
+    | **正例** | **反例** |
+  | -------- | -------- |
+  | 接通开发板电源。 | 按下开发板电源开关。 |
+
+- 避免使用含义模糊的词，如表示程度、强调等语气的词。
+    | **正例** | **反例** |
+  | -------- | -------- |
+  | 无 | -&nbsp;表示程度的词：较多（more）、较好（better）、基本地（basically）、决定性的（decisively）、最后的&nbsp;&nbsp;(&nbsp;finally&nbsp;)、很（very）、可能（may/maybe/could）、大概（probably）、通常(&nbsp;usually&nbsp;)、一般&nbsp;&nbsp;(&nbsp;generally&nbsp;)。<br/>-&nbsp;表示转折的词：当然（of&nbsp;&nbsp;course）、然而（however）。<br/>-&nbsp;表示量的词：有些（some）、非常（very）、大量（large&nbsp;&nbsp;number）、一些（several）、少许（few）。 |
+
+【规则】确保逻辑清晰：
+
+- 采用合理的逻辑结构（写作顺序），使章节/段落/步骤/句子顺序符合用户认知习惯。以下常用写作顺序可以独立使用，也可配合使用。
+    | **逻辑结构（写作顺序）** | 特征 | 适用的典型信息类型（不限于） |
+  | -------- | -------- | -------- |
+  | 先总后分 | 先综述总论点（如特性概述、开发流程概述），再依次展开分论点（子特性详细介绍、开发任务流详细介绍）。<br/>总论点下的分论点做到完全穷尽（不遗漏）、相互独立（无交叠）。 | 功能/场景描述类<br/>开发指导类 |
+  | 按时间顺序 | 时间、流程或因果上的有先有后。 | 开发指导类 |
+  | 按空间/结构顺序 | 从上层到下层；从整体到局部。 | 架构描述类<br/>组网描述类 |
+  | 按重要性顺序 | 从重要到次要；从基础到特殊。 | 开发指导类<br/>问题分析类 |
+  | 按"情境-冲突-问题-回答"顺序 | 通过追溯问题的起源和发展，引入用户熟悉的情境，然后说明冲突，从而提出最初的问题，最后给出解决方案（也就是即将阐述的主题）。 | 功能/场景描述类 |
+
+- 对于开发指导类内容，能让用户直观了解具体场景/任务的完整开发流程。
+
+- 对于存在分支的步骤，提供明确的选取原则。
+
+- 适当使用图、表，使逻辑和表意更直观。
+
+
+## 一致

+# HAP编译构建指导
+
+## 概述
+
+### 基本概念
+| 术语 | 含义 |
+| -------------- | ---------------------- |
+| HAP            | OpenHarmony Ability Package，一个HAP文件包含应用的所有内容，由代码、资源、三方库及应用配置文件组成，其文件后缀名为.hap。 |
+| Ability        | 应用的重要组成部分，是应用所具备能力的抽象。Ability是系统调度应用的最小单元，是能够完成一个独立功能的组件，一个应用可以包含一个或多个Ability。 |
+| FA             | Feature Ability，是FA模型的Ability框架下具有UI界面的Ability类型，用于与用户进行交互。Feature Ability唯一对应一种模板，即Page模板（Page Ability）。 |
+| PA             | Particle Ability，是在FA模型的Ability框架下无界面的Ability，主要为Feature Ability提供服务与支持，例如作为后台服务提供计算能力，或作为数据仓库提供数据访问能力。Particle Ability有三种模板，分别为Service模板（Service Ability）、Data模板（Data Ability）、以及Form模板（Form Ability）。 |
+| FA模型         | 两种Ability框架模型结构的其中一种。是Ability框架在API 8及更早版本采用FA模型。FA模型将Ability分为FA（Feature Ability）和PA（Particle Ability）两种类型，其中FA支持Page Ability模板，PA支持Service ability、Data ability、以及Form ability模板。详情可参考[FA模型综述](../../application-dev/ability/fa-brief.md)。 |
+| Stage模型 | 两种Ability框架模型结构的其中一种。从API 9开始支持。Stage模型将Ability分为Ability和ExtensionAbility两大类，其中ExtensionAbility又被扩展为ServiceExtensionAbility、FormExtensionAbility、DataShareExtensionAbility等等一系列ExtensionAbility。 |
+
+### 功能简介
+提供HAP编译构建功能，支持FA模型、Stage模型。
+
+## 开发指导
+
+### 编译系统提供的模板
+#### ohos_hap
+
+声明一个HAP目标，该目标会生成一个HAP，最终将会打包到system镜像中。
+
+| 支持的变量 | 说明 |
+| --------- | ---- |
+| hap_profile | HAP的config.json，Stage模型对应module.json。 |
+| raw_assets | 原始assets，这些assets会直接拷贝到HAP的assets目录下。 |
+| resources | 资源文件，编译后放置在assets/entry/resources目录下 |
+| js_assets | js资源，ace编译后放置在assets/js/default目录下。|
+| ets_assets | ets资源，ace编译后放置在assets/js/default目录下 |
+| deps | 当前目标的依赖 |
+| shared_libraries | 当前目标依赖的native库 |
+| hap_name | HAP的名字，可选，默认为目标名 |
+| final_hap_path | 用户可以制定生成的HAP的位置，可选，final_hap_path中会覆盖hap_name。|
+| subsystem_name | HAP从属的子系统名，需要和ohos.build中的名字对应，否则将导致无法安装到system镜像中。|
+| part_name | HAP从属的部件名，同subsystem_name。|
+| js2abc | 是否需要将该HAP的js代码转换为ARK的字节码。|
+| ets2abc | 是否需要将该HAP的ets代码转换为ARK的字节码。|
+| certificate_profile | HAP对应的授权文件，用于签名。|
+| certificate_file | 证书文件，证书文件和授权文件，应用开发者需要去openharmony官网申请。|
+| keystore_path | keystore文件，用于签名。|
+| keystore_password | keystore的密码，用于签名。|
+| key_alias | key的别名。|
+| module_install_name | 安装时的HAP名称。|
+| module_install_dir | 安装到system中的位置，默认安装在system/app目录下。|
+| js_build_mode | 可选，用于配置HAP是“release”还是“debug”模型编译，默认“release”。|
+
+#### ohos_app_scope
+声明一个HAP的AppScope模块，该目标的app_profile和sources会在编译时拼接到具体的entry内编译，该模板只在Stage模型下使用。
+
+| 支持的变量 | 说明 |
+| --------- | ---- |
+| app_profile | HAP的AppScope中的app.json，只在Stage模型下使用。|
+| sources | HAP的AppScope中的资源resources，只在Stage模型下使用。|
+
+#### ohos_js_assets
+js或ets代码，ace编译后放置在assets/js/default目录下，stage模型根据代码分别放置到js或ets目录。
+
+| 支持的变量 | 说明 |
+| --------- | ---- |
+| hap_profile | HAP的config.json，Stage模型对应module.json。|
+| source_dir | js或ets代码路径，兼容FA模型的单ability配置到ability目录。|
+| ets2abc | 当前为ets代码，主要用于卡片配置，其他应用可不配，使用ohos_hap中的配置。|
+| js2abc | 当前为js代码，主要用于卡片配置，其他应用可不配，使用ohos_hap中的配置。|
+
+#### ohos_assets
+原始assets，这些assets会直接拷贝到HAP的assets目录下。
+
+| 支持的变量 | 说明 |
+|---------- | ---- |
+| sources | 原始assets的路径。|
+
+#### ohos_resources
+资源文件，FA模型编译后放置在assets/entry/resources目录下，Stage模型编译后放置在resources目录下。
+
+| 支持的变量 | 说明 |
+| --------- | ---- |
+| hap_profile | HAP的config.json，Stage模型对应module.json。|
+| sources | 资源文件路径。|
+| deps | 当前目标的依赖。Stage模型需要配置对ohos_app_scope目标的依赖。|
+
+### 操作步骤
+
+1. 将开发完成的应用example放到applications/standard/目录下。
+
+2. 配置gn脚本applications/standard/example/BUILD.gn，FA模型简单示例如下（更多BUILD.gn配置见[gn脚本配置示例](#gn脚本配置示例)）：
+   ```
+   import("//build/ohos.gni") # 引用ohos.gni
+
+   ohos_hap("example") {
+     hap_profile = "./src/main/config.json" # config.json
+     js_assets = ["./src/main/js/default"]
+     raw_assets = ["./raw_assets"]
+     resources = ["./src/main/resources"]
+     shared_libraries = [
+       "//third_party/libpng:libpng", # native库
+     ]
+     certificate_profile = "../signature/systemui.p7b" # Cer文件
+     hap_name = "SystemUI-NavigationBar" # 名字
+     part_name = "prebuilt_hap"
+     subsystem_name = "applications"
+   }
+   ```
+
+3. 修改applications/standard/hap/ohos.build，示例如下：
+   ```
+   {
+     "subsystem": "applications",
+     "parts": {
+       "prebuilt_hap": {
+         "module_list": [
+           ...
+           "//applications/standard/example:example" # 添加编译目标
+         ]
+       }
+     }
+   }
+   ```
+
+4. 编译命令：
+   ```
+   # 全量编译
+   ./build.sh --product-name {product_name}
+
+   # 单独编译HAP
+   ./build.sh --product-name {product_name} --build-target applications/standard/example:example
+   ```
+
+5. 编译产物，FA模型简单例子HAP解压视图如下：
+   ```
