字节流对象模型的设计和应用

Design and Application of Bytes Object Model

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 space technology makes higher demands on mission data processing. Given that the formats of mission data are hierarchical and nested structures,and change frequently,Bytes Object Model （BOM）is designed based on Composite pattern. BOM model has the advantage of strong expressiveness and flexible extensibility. That this model is utilized in Space Mission Data Process Software makes the software have exceUent ability of extension.
