供仿效,代码还可继续打磨

近些日子要在ABAP中实现 3DES 标准对称加密算法,与另外外界系统开展加密/解密操作。由于ABAP语言中尚无 左移 <<、无符号右移 >>>  操作,只好自身达成

供参照他事他说加以考察,代码还可继续打磨

假若运动的位数bit是字节(8位)的子弹头倍,则直接使用  SHIFT <i> BY p PLACES PAJEROIGHT IN BYTE MODE.这样的语句消除(那样成效会越来越高),若是非字节整几倍,则供给借助SET BIT来产生,实现时,要留神整型的字节序格式,本身支付条件是低字节序(低位在前,高位在后),与人的阅读习于旧贯是反的(但要注意的字节里面包车型地铁是依旧高位在前,低位在后),左右位移法则如下(同一种颜色为运动后所在地点):

Background

When I was developing an application for Pocket PC that used quite large DataSet, I wondered where I could gain at least some bits of performance. I was filling some data to a tree view control, storing some data else, doing selects from DataTable and getting the data from columns of DataRows. As you know, you can access the DataRow's columns by using either string indexing (dataRow["NAME"] or integer indexing dataRow[3]).

I thought I could test performance of both indexers - I just wanted to know if I could still use string indexers (they are more comfortable to work with) - or to rework the code of this app to use integer indexing. So here comes the performance tester.
