摘　　要：DDS(数据分发服务)是一款广泛使用的发布订阅通信中间件,然而其使用的IDL语言只能描述接口数据类型,缺乏对分布式系统建模的能力,因此对IDL语言进行语法扩展,引入应用描述XML文件,实现对DDS分布式系统的建模。进一步提出并实现解析新的IDL文件和应用描述XML文件的编译器,自动生成代码并编译成动态链接库或Lua解释器,解耦设计和开发,简化发布订阅API,降低开发工作量。DDS(data-distribution service)is a widely used communication middleware with the publish/subscribe pattern.However IDL,the language used by DDS,only describes the interface data types without the ability of modeling a system.To achieve the ability,the grammar of IDL was extended and application description XML files were introduced.Moreover,a new compiler was proposed and implemented.IDL and XML files were compiled to shared libraries or Lua interpreters.The compiler decoupled the process of design and development,and the compiled product offered simplified APIs which reduced programming workload.
