QT CTK插件开发(六) 多对一插件

news2024/12/25 2:02:24

        CTK在软件的开发过程中可以很好的降低复杂性、使用 CTK Plugin Framework 提供统一的框架来进行开发增加了复用性 将同一功能打包可以提供多个应用程序使用避免重复性工作、可以进行版本控制提供了良好的版本更新迭代需求、并且支持动态热拔插 动态更新、开发更加简单快捷 方便有用的开发，方便公司的持续技术积累和代码、模块、功能的统一管理和持续更新完成，对于企业实际开发过程中有比较重要的意义。

        本专栏文章较为全面的讲述了CTK插件开发的全部步骤，包括不限于 CTKPlugin插件、服务-接口(一服务对一接口)、服务-接口(多服务对一接口)、服务-接口(多接口对一服务)、CTK插件批量加载、CTK插件热拔插、CTK事件监听、CTK事件发送-类通信、CTK事件发送-信号槽、CTK版本控制、CTK版本控制、CTK插件元数据、CTK 服务工厂、CTK 服务追踪、控制中心软件开发CTK 等文章；

        CTK Plugin Framework基于Qt Plugin System和Qt Service Framework实现，并且增加了以下特性来扩展：插件元数据（由MANIFEST.MF文件提供）、一个定义良好的插件生命周期和上下文、综合服务发现和注册；

        Plugin System：CTK Core依赖于QtCore模块，CTK Plugin Framework基于Qt Plugin System。Qt API允许在运行时加载和卸载插件，热插拔功能在CTK Plugin Framework中得到了加强，以支持透明化延迟加载和解决依赖关系。

        插件的元数据被编译进插件内部，可以通过API进行提取。此外，插件系统还使用SQLite缓存了元数据，以避免应用程序加载时间问题。另外，Plugin System支持通过中央注册中心使用服务。

        Service Registry：Qt Service Framework是Qt Mobility项目发布的一个Qt 解决方案，Qt服务框架允许“声明式服务”和按需加载服务实现。为了启用动态（非持久性）服务，Qt Mobility服务框架可以与Service Registry一起使用。       

        本文是 QT CTK开发 第六篇文章，演示了

    CTK 开发优点
    降低复杂性：使用CTK开发只需进行插件开发，插件隐藏了内部实现，开发变得更加简单，因为只需要实现功能接口即可。
    可复用：标准化的组件模型，一个插件多个软件使用。
    版本控制：所有插件都经过严格的版本控制，只有能够协作的插件才会被连接在一起。
    动态更新：OSGi组件模型是一个动态模型，插件可以在不关闭整个系统的情况下被安装、启动、停止、更新和卸载。
    自适应：OSGI动态服务模型允许插件找出系统中可用的功能，并调整它们所能提供的功能，使得代码更加灵活， 并且能够更好地适应变化。
    透明性：插件和服务是CTK插件环境中的一等公民。管理API提供了对插件的内部状态的访问，以及插件之间的连接方式。
    开发简单：CTK插件相关的API非常简单，核心API不到25个类。核心API足以编写插件、安装、启动、停止、更新和卸载，并且还包含了所有的监听类。
    懒加载：插件可以用饿汉式启动，但是也可以被配置为仅当其它插件使用它们时才启动。服务可以被注册，但只有在使用时才创建。懒加载场景可以节省大量的运行时成本。
    非独占性：CTK Plugin Framework不会接管整个应用程序，可以选择性地将所提供的功能暴露给应用程序的某些部分。
    非侵入：在一个CTK插件环境中，不同插件均有自己的环境。插件可以使用任何设施，框架对此并无限制。

    CTK Plugin Framework不仅仅是组件的标准，还指定了如何安装和管理组件的API。API可以被插件用来提供一个管理代理，管理代理可以非常简单，如命令shell、图形桌面应用程序、Amazon EC2的云计算接口、或IBM Tivoli管理系统。标准化的管理API 使得在现有和未来的系统中集成CTK Plugin Framework变得非常容易。
