StarBus中接口定义语言编译器的设计与实现

The Design and Implementation of IDL Compiler in StarBus

从阐述接口定义语言(IDL)编译器在CORBA开发模型中的地位和作用开始，提出了IDL编译器的设计框架，将其分为编译器前端(CFE)和后端(BE)。然后详细说明了IDL编译器中用到的接口池的数据结构，并介绍了CFE和BE的实现过程。在介绍BE的实现时，着重说明了它用到的Narrowing机制。最后，说明了IDL编译器(到C++ Mapping)的使用环境。

Begin with the Interface Definition Language(IDL) compiler's position and tribute in CORBA development model,this paper explore an IDL compiler framework,which is divided into compiler front end(CFE) and back end(BE). The interface repository which is used in IDL compiler is interpreted in detail,so is the implementation of CFE and BE. While discussing the implementation of BE,we put more attention on the Narrowing mechanism used in it. Finally, this paper ended with the develop environment of this IDL(to C++ Mapping) compiler.
