An object is said initialization. — end note] The lifetime of an object of type T begins when: (1.1) — storage with the proper alignment and size for type T is obtained, and (1.2) — if the object has non-vacuous initialization, its

Data fields of classes should be initialized in the Flush() override { puts("USBC Flush"); } }; int main() { Note, I'm creating a USBC object and store it as IOPort std::unique_ptr port{std::make_uniqueFlush();

# Object Pascal 参考手册 (Ver 0.1) ezdelphi@hotmail.com ## Overview（概述） ## Using object pascal（使用 object pascal） Object Pascal 是一种高级编译语言，具有强类型（对数据类型的检查非常严格）特性，支持结构化和面向对象编程。它的优点包括代码的易读性、快速编译，以及支持多个单元文件从而实现模块化编程。 而实现模块化编程。 Object Pascal 具有一些特性以支持 Borland 组件框架和 RAD（快速应用程序开发）环境。在很大程度上，本语言参考的说明和示例假定你使用 Borland 公司的开发工具，如 Delphi 和 Kylix。 绝大多数使用 Borland 开发工具的开发者是在 IDE（集成开发环境）环境下编写代码并进行编译。Borland 开发工具帮助我们设置工程和源文件的许 限制，严格说来，这不是 Object Pascal 语言规范的一部分。比如，Borland 开发工具遵循某些文件和程序的命名约定，若你在 IDE 以外编写代码并使用命令行来编译，你可以避开这些限制。 这些帮助主题假设你在 IDE 环境下工作，并且使用 VCL（可视化组件库）和/或 CLX（跨平台组件库）创建应用程序。但有时候，Borland 一些特定的规则和 Object Pascal 的通用规则并不相同。
