Refactoring data flow applications without source code changes or recompilation

Systems and methods may provide refactoring data flow applications without source code changes or recompilation. An apparatus may create a map file that describes how an original graph structure and node properties are mapped to a new structure and set of properties. A runtime system aware of the mapping may transform a graph that is constructed by the data flow application into the new structure at runtime. 系统和方法可以在没有源代码改变或重新编译的情况下提供重构数据流应用。装置可以创建映射文件，映射文件描述原始图形结构和节点属性如何映射到新的结构和属性集。了解该映射的运行时系统可以在运行时将由数据流应用构造的图形转换为新的结构。
