Note : for comparison , the key is used in the first function and the value is used in the second . they are both user - made functions 注意：这里参与比较的是第一个函数中的键和第二个函数中的值。它们都是用户自定义函数。
This is true for all built - in exceptions , but need not be true for user - defined exceptions ( although it is a useful convention ) 对于所有的内置异常都是如此，不过用户自定义异常就不一定了（尽管这是一个很有用的约定） 。
Note : both the key and the value is used in the automatic comparison , then , in the user - defined function , only the keys are being compared 注意：如果是默认情况下，将同时对键和值进行比较；此时，在用户自定义函数中，仅对键进行比较。
The array _ map ( ) function sends each value of an array to a user - made function , and returns an array with new values , given by the user - made function 函数将一个数组中的每个值都发送到用户自定义函数中，并返回这个自定义函数中的数组值。
A comprehensive index and search capability . with the oracle data base , each base can have up to 30 categories of the user - defined searching features 全面的索引和查询能力，采用oracle数据库，每个库最多可以有30类用户自定义的搜索属性特征
The construct that handles user - defined logic in sax parsing . you will understand the sax package structure , see its relation to the sax 本技巧详细介绍了创建sax contenthandler的过程， sax contenthandler是在sax分析中处理用户自定义逻辑的构件。
Layouts that will be modified or generated dynamically at run time , such as data entry forms that have user - customizable fields added or subtracted based on preferences 将在运行时动态修改或生成的布局，如根据首选项增减了用户自定义字段的数据输入窗体。
Because pmac provides the function that is for custom user - written algorithms , i define the algorithms which are different from the algorithm pmac has 利用pmac控制器的优势,扩展了用户自定义控制算法。将这些控制方法应用到实验系统中,实现了较好的控制效果。
The corresponding user - defined function is called , with an argument list that is one longer than the argument list of the call : the instance becomes the first argument 调用对应的用户自定义函数，其参数个数比普通的函数调用多一：该实例成为方法的第一个参数。
Customer - defined ivr : customized ivr system is available for you , for example , " this is xxx company , please dial the extension number " , or setup an customer enquiry center 呼叫转移:用户自定义将所申请国际号码的来电呼叫转移到任何电话号码（移动、固话、小灵通等） 。
