Method is used by custom server controls that do not allow tag or attribute mapping and render markup elements in the same way for each request 方法，这种自定义服务器控件不允许标记或属性映射并以相同的方式为每个请求呈现标记元素。
This means the complex data structures can be represented as classes and the web services stack will automatically map the class attributes to the data types defined in the wsdl file 这意味着复杂的数据结构可以表示成类， web服务栈能够自动将类属性映射到wsdl文件中定义的数据类型。
It is the responsibility of the control to cast or convert the value to the appropriate type and carry out further processing such as mapping data from an old property to a new property 由控件负责将值强制转换或转换为适当的类型并执行进一步的处理（比如将数据从旧的属性映射到新的属性） 。
In the context of the el , however , the character string associated with an attribute can also be thought of as the name of a variable , which is bound to a particular value by means of the attribute mappings 。但是，在el的上下文中，也将与属性相关联的字符串看作变量的名称，该变量通过属性映射的方式获得特定的值。
These theorems is the basis and guideline for constructing and verifying the weak derivation set according to the invertibilrty of attribute mapping , thus improves the basic theories of data lineage tracing 这些定理为作者根据属性映射的可逆性构造和验证弱起源集提供了基本依据和指导思想，丰富了数据志跟踪的基本理论。
In the second part of the object - relational mapping see table 2 , classes are mapped to tables , scalar properties are mapped to columns , and pointer reference properties are mapped to primary key foreign key relationships 对象-关系映射的第二部分（参见表2 ）中，类映射到表，标量属性映射到列，指针/引用属性映射到主键/外键关系。
Next , this thesis presents a data lineage tracing approach , wivem ( weak inversion and verification of attribute mapping ) , which can calculate ( attribute - level ) derivation set of attribute mapping 作者根据可逆与弱可逆的思想，提出了一种“基于属性映射的弱逆与验证的方法( wivem ， weakinversionandverificationofattributemapping ) ”求解属性映射的(属性级)起源集。
Rather than supporting direct mapping of object - oriented classes and properties to relational tables and columns , the entity framework maps relational tables , columns , and foreign key constraints to entities and relationships in conceptual models 与直接将面向对象的类及其属性映射成关系型数据表和列不同，实体框架将数据库内的关系表、列以及外键约束映射成概念模型里的实体和关系。
The more advanced developers might also like to generate javabeans mapping attributes to table columns , and it would also be nice to generate data access objects providing methods for querying and updating data in the database 更高级的开发者可能还喜欢生成javabeans （ tm ） ，以将属性映射到表中的列，如果能生成数据访问对象（ data access object ） ，从而为查询和更新数据库中的数据提供方法，那也是很方便的。
Then this thesis proves five theorems about derivation set , which defined the relationship between transformation and attribute mapping , derivation set and attribute mapping , derivation set and contribution set , and the correlation of supplementary set of transformation 在此基础上，作者证明了有关起源集的5个定理，这些定理证明了转换与属性映射、起源集与属性映射、起源集与作用集之间的关系，并证明了几类转换的补集无关性。
