ISO 10303的本部分规定了标准中规定的功能接口的实现 数据访问接口（SDAI），ISO 10303-22，用C++语言编写。 以下内容属于ISO 10303本部分的范围: -访问和操作ISO 10303-22中规定的数据类型和实体； -适合这种语言绑定的便利功能； -将函数绑定到ISO 10303-22中规定的操作和属性 应用程序模式定义在两个编译- 时间或运行时； -ISO 10303-22中规定的错误处理实施机制； -ISO 10303-22中规定的约束验证实施机制。 以下内容不在ISO 10303本部分的范围内: -ISO 10303-22中列出的超出范围的所有项目。

This part of ISO 10303 specifies the implementation of the functional interface specified in the standard data access interface (SDAI), ISO 10303-22, in the C++ programming language. The following are within the scope of this part of ISO 10303: — access to and manipulation of data types and entities which are specified in ISO 10303-22; — convenience functions suitable to this language binding; — binding of functions to operations and attributes specified in ISO 10303-22 with the linking of application schema definition at either compile-time or run-time; — implementation mechanisms for the handling of errors as specified in ISO 10303-22; — implementation mechanisms for the validation of constraints as specified in ISO 10303-22. The following is outside the scope of this part of ISO 10303: — all items listed as out of scope in ISO 10303-22.
