There is no automatic conversion to or from any structure data type 其他数据类型与任何结构数据类型之间不会进行任何自动转换。
Structure data types have no literal type character or identifier type character 结构数据类型没有文本类型字符或标识符类型字符。
The default value of a structure data type consists of the combination of the default values of each of its members 结构数据类型的默认值由它的每个成员的默认值组合而成。
Define and use a structure data type when you need to combine various data types into a single unit , or when none of the elementary data types serve your needs 当您需要将不同的数据类型组合为一个单元时,或者当所有基本数据类型都无法满足您的需求时,可以定义和使用结构数据类型。
3 . schemas for semistructured data differ , however , from those for relational or object - oriented data . therefore , typing system and schema formalisms for xml - based semistructured data are extensively studied , and the algorithms both for computing type classification with maximal fixpoints semantics and maximal simulation are proposed , respectively 三、对半结构数据的类型及模式的描述形式进行了研究,并分别给出了使用最大不动点语义计算半结构数据类型划分的算法思想和最大仿真( simulation )计算方法的思想。
Finally , considering the problem which the cipher ' s secure level is not easy to be changed in the existing elliptic curve digital signature field - arithmetic algorithms , we express a large number as the structure data type and design a field - arithmetic algorithm in elliptic curve cryptography for different cipher security 第四是针对现广西大学硕士学位论文一基于椭圆曲线密码体制的多重数字签名技术研究有的椭圆曲线密码体制密码域算术算洁在实现上强度不易扩展的问题,我们将大整数用结构数据类型表示,设计适合不同椭圆曲线密码强度的域算术算洁。
