For the most part, though, this type of solution still requires some custom code to work with an organization's specific problem, actually transforming this into a services type of solution.
但对于大多数情况，这类解决方案仍然需要一些自定义的代码，以处理组织中特定的问题，实际上将其转换成了服务类型的解决方案。
This allows user code to be ported between frameworks, but not the generated classes — those are specific to a particular data binding framework and will only operate with that framework.
这使用户代码可以在各框架之间进行移植，而不需移植生成的类—这些类特定于专门的数据绑定框架，它们只能由该框架运行。
While you could develop a class that implements all three interfaces, you end up with quite a lot of technology-specific code for accessing and processing the actual messages.
当您能开发一个类来实现所有这三个接口时，会以访问、处理实际消息的代码而结束，而这些代码又与许多与技术细节是紧密相关的。

现在，使用JAXP 1.3可以解析、验证并转换XML，而无需编写一行特定于开发商的代码。
I have found that being able to report these exceptions with a specific error code (instead of a generic exception or, even worse, no reported error) has saved me hours tracking bugs.
我发现，在跟踪错误时，用特定的错误码(而不是一般的异常或—甚至更糟—不报告错误)来报告这些异常节省了我数小时的时间。
Before we can do anything String-specific with that retrieved value, we have to cast it to a String, even when the retrieved element was added in the same code block!
在对检索到的值进行任何特定于String的操作之前，必须将它强制转换为String，即使是将检索到的元素添加到同一代码块中，也是如此！
In order to combine the EPC and the the master data, a solution-specific code component called handler needs to be written to interpret the EPC and look up the correct MDM entity with an external ID.
为了组合EPC和管理数据，需要编写一个称为处理器(handler)的解决方案特定的代码组件，这个组件解释EPC并用外部ID查找正确的MDM实体。
Azure Grid provides you with a base solution template to which you add application-specific code.
AzureGrid为你提供了一个基础的解决方案模板，在其中你可以添加特定于应用程序的代码。
select a specific communication protocol or API that can interoperate with non-SCA code. Because of this, bindings other than the default binding are often called interoperable bindings.
正因为如此，非缺省的绑定通常被称为可互操作的绑定。
Dear friends, with the popularity of two-dimensional code, after your home house also has a two-dimensional code! Scan two-dimensional code to check your specific address information.
各位朋友们，随着二维码的普及，以后你家的门牌上也有二维码啦！扫描二维码即可查你家的具体地址信息。
In this case, the object typically has a property that contains the specific error code associated with the error.
在那种情况下，对象通常有一个属性包含与错误关联的特定错误代码。
