航天技术的快速发展对任务数据处理提出了更高的要求。针对任务数据格式具有层次嵌套、变化频繁的特点,结合Composite模式设计了字节流对象模型(BOM)。BOM模型具有表述能力强、可灵活扩展的优点。该模型在航天任务数据处理软件中得到了应用,使得软件具备较好的可扩展能力。
The rapid development of aerospace technology put forward higher requirements for mission data processing. According to the characteristics of task data format being nested hierarchically and changing frequently, byte stream object model (BOM) is designed with Composite mode. BOM model has the ability to express strong, flexible expansion. The model has been applied in space mission data processing software, which makes the software have better scalability.
