映射对象

• If the positional argument is a mapping object , return a dictionary mapping the same keys to the same values as does the mapping object
  如果位置参数是一个映射对象，则返回像映射对象一样的键值映射。
• When you run ipdrive , it will load the inproc sample and create a variant map object that you can manipulate using ipdrive s interface
  在运行ipdrive时，它将加载inproc示例并创建变量映射对象，您可以使用ipdrive的接口操纵该映射对象。
• If the primary is a mapping object ( e . g . , a dictionary ) , the subscript must have a type compatible with the mapping ' s key type , and the mapping is then asked to create a key / datum pair which maps the subscript to the assigned object
  如果主元是一个映射对象（比如字典） ，下标的类型必须和映射的键类型兼容，接着该映射就被要求创建一个把下标映射到被赋对象的键/数据对。
• In the part of image encryption , chaotic map based on kolmogorov flow is used to permute . changing the traditional stream - cipher , new chaotic pseudo - random sequence generator based on the theory of product cipher is presented to substitute the pixel . based on it , linear map to confuse the pixel is presented further , withstanding statistical attack
  在图像加密方面,采用基于kolmogorovflows的混沌映射对图像进行置乱,对传统流加密进行改造,提出了基于乘积密码理论的新型混沌伪随机序列发生器完成象素的混淆,并在此基础上进一步采用线性映射对象素进行扩散以抵抗统计攻击。
• Then , o / r mapping solution is highlighted and a generalized mapping mode from object to relation table , including mapping object , constraint condition , mode / pattern language . based on this pattern , the basic strategy from all kinds of appearance to relation table has been analyzed in detail
  之后，重点介绍了o rmapping的解决方案，提出了一个从对象(类)到关系表映射的一般模式，包括映射对象、约束条件、模式语言等；并以此模式为基础，详细分析了对象理论中各种形态(聚合、继承和关联)到关系表中映射的基本策略。
