The powerful as operator in Groovy takes a code block and generates a new class that implements the interface, which you can then call as if it were a concrete class implementing the interface.
Groovy中强大的as操作符接收一个代码块并生成一个新类来实现该接口，您可以像调用实现该接口的具体类一样调用它。
For an example, see the.net Framework documentation for the CryptoStream class, which shows you how to encrypt a byte array from an incoming FileStream object.

Then you can continue narrowing down to determine which package, class, and, finally, which method is causing the problem.
然后您可以继续进行分析，把范围缩减到哪个包、类，直到找到导致问题的方法。
Another helpful addition to PHP V5 is the abstract class, which makes it easy to have one base class to implement the core of an interface from which you then create concrete classes.
PHPV 5中另一个有帮助的新功能是抽象类，使用抽象类可以轻松地用一个基类实现接口的核心部分，然后用该接口创建实体类。
Note that with tag-class selectors, you can add them only to the tag for which you defined the class.
注意，如果使用标记类，那么只能把这些类添加到定义的相关标记中。
In this way, you can change the concrete class later without changing the library code, which relies solely on the definition you created in the interface.
这样，日后就可以在不改变库代码的情况下修改具体的类，因为库只依赖接口中创建的定义。
Notice the Interfaces text area, in which you can enter any interface you want this class to implement.
注意在接口文本区域可以输入任何你希望该类实现的接口。
