【摘要】 首先用数学语言描述CDR的边界对齐原则,对若干开源JavaORB系统的TypeCode编码问题进行了论述。重点提出并证明了CDR编码的字节流在复制过程中表现的两个数学特征,利用此特征提出复制CDR编码字节流的高效改进方法。对改进前后以及不使用边界对齐时的性能进行测试,说明改进方案取得了较好效果。更多还原

【Abstract】 The paper begins with a mathematical description of CDR alignment before a discussion about a CDR problem of TypeCode in some free Java ORBs, then focuses on the proof of two important characteristics about alignment in CDR stream data copying. The results can be applied to CDR implementation and improve its performance, which is verified by performance test on several possible implementations of CDR. ’更多还原
