1·Transparency: The pre - and post-condition code isn't mixed with business logic.

透明性：前置和后置条件代码不与业务逻辑混合。

2·If a user is not authenticated when trying to access this resource, the user will receive a 401 status code and the application can provide a special error handler to deal with that condition.

如果用户在尝试访问这个资源时还没有经过身份验证，那么用户会收到401状态码，应用程序可以提供一个特殊的错误处理函数来处理这种情况。

3·So double bar means if this condition or this one — and maybe even both — are true, go down this road and execute that code.

所以复纵线意思是，如果这两个条件之一-，或者两个都——是成立的，那就继续，执行后面的代码。

4·Creation of the rule essentially means creating the rule target and the condition; these are also demonstrated with their own code listings.

创建规则实质上意味着创建规则目标和条件，这些都使用它们自己的代码清单作了说明。

5·You can measure code coverage in several ways: by assessing line or statement coverage, condition coverage, branch coverage, and so on.

您可以通过许多方法来测量代码覆盖率：通过评估代码行或语句的覆盖面、条件覆盖面、分支覆盖面等等。

6·The programmer can immediately see if a condition is not going to be met and take corrective measures before running the code.

这样程序员就可以立即得知条件是否得到满足，并在运行代码之前进行一定调整。

7·Figure 3 shows the results of running the example code above, showing the results of a memory condition: memory leak condition.

图3显示了运行上述示例代码的结果，其中显示了“内存条件：内存溢出”条件的结果。

8·The code in Listing 4 illustrates creation of the condition.

清单 4 中的代码说明了条件的创建。

9·Fundamentally, each of these does exactly the same thing: it tests a condition, and if true, continues to execute the block of code provided.

它们做的基本上是同一件事：测试一个条件，如果该条件为真，则继续执行提供的代码块。

10·Sometimes a piece of code is called many times, even from different threads, but you only want to stop in that code if a particular condition is met.

有时有一段代码会得到多次的重复访问，有时甚重由不同的线程访问，但是如果达到某种特定的状况时，您只想停止其中的一段代码。
