Make sure that there is only one line that is a super method invocation.
相反，类方法不需要您创建一个示例。
In contrast, class methods do not require you to create an instance.
超类方法——在运行时不需要其他实例。

对于实际的时间戳转换，我们使用了下面的类方法。
For the actual timestamp conversion the following class method was used.
这就是类方法为了进行时间戳转换而在内部使用的值。
That is the value that would be used internally by the class method for the timestamp conversion.
第一类方法使用任意的xml片段，如下所示。
In one class, some of the methods work with arbitrary fragments of XML, as follows.
图2中的第二类方法则操纵元素中的属性。
The second class of method in Figure 2 comprises methods that manipulate attributes within elements.
用于类方法并返回函数的用例仅利用您的创造力进行限定。
The use cases for class methods that return functions is limited only by your creativity.
如果__ call失败，就调用父类方法，依此类推。
If __call fails, the parent class method is invoked, and so on.
另外，这个库还提供以不同方式创建类型的对象的类方法。
In addition the library provides class methods to create objects of their type in different ways.
这意味着存储过程不同于类方法，因为它们不是表的一部分。
This would imply that stored procedures are not similar to class methods since they are not part of tables.
相反，可以在Web服务类方法中使用以下内容作为参数或返回值。
Conversely, you can use the following as parameters or return values in a Web service class method.
类的API目前包含对于继承和超类方法调用的完善支持。

一般来讲，可以通过类方法或实例方法的调用来获得对象引用。
Generally, object references can be obtained by the invocation of a class method or instance method.
现在让我们了解一下四个有用的函数，并演示其他str类方法的工具。
Instead, let's look at four functions that are useful in their own right and demonstrate the utility of the rest of the STR class methods.
同样，您几乎总是在子代方法主体的开始或结束部分调用超类方法。
Likewise, you almost always call a superclass method at either the start or end of a descendent method body.
Ruby还包括另外一个方便的DSL机制：alias_method类方法。
Ruby also includes another handy DSL mechanism: the alias_method class method.
在本文中，我讨论了延迟静态绑定、名称空间支持、类方法重载和heredoc支持。
In this article, I looked at late static binding, namespace support, class method overloading, and heredoc support.
确定代码库中类方法的CC并连续监视这些值将使您的团队在复杂问题出现时抢先处理它们。
Determining the CC of class methods in a code base and continually monitoring these values will give your team a head start on addressing complexity issues as they arise.
第二行(在Python 2.2及以上版本中)告诉Psyco对类方法执行相同的操作。
The second line (in Python 2.2 and above) tells Psyco to do the same with class methods. To target Psyco's behavior a bit more precisely, you can use the commands.
