1.关于<init>与<clinit> At the level of the Java Virtual Machine, every constructor written in the Java programming language (JLS §8.8) appears as an instance initialization method that has the special name <init>. This name is supplied by a…

特殊方法 特殊方法的存在是为了给 Python 解释器调用的,通常自己并不需要直接调用它们.也就是说不应该使用 my_object.__len__() 这种写法,而应该使用 len(my_object)调用.在执行 len(my_object) 的时候,如果 my_object 是一个自定义类的对象,那么 Python 解释器会去调用所属类其中的 __len__ 方法. 然而,如果my_object是 Python 内置的类型,如list.str.bytearray 等,那么 Python 解释…

Java Native Interface(JNI) allows Java applications to call native methods, which are special methods written in native programming languages such as C or C++. Historical usages of native methods Access to platform-specific facilities such as registr…

17.1 Object-oriented featuresPython is an object-oriented programming language, which means that it provides features that support object-oriented programming.It is not easy to define object-oriented programming, but we have already seen some of its…

The first thing to know about special methods is that they are meant to be called by the Python interpreter, and not by you. You don't write my_object.__len__(). You write len(my_object) and, if my_object is an instance of a user-defined class, then…

对特殊方法的访问 - Special method lookup 对于用户自定义的 class 来说, 特殊方法只有通过定义对象的类型object’s type (而非通过 instance 的 __dict__属性)被定义, 才能保证特殊方法的隐式调用. 也就是说给自定义的 class 打 特殊方法的 monkey patching 后,再通过 conventional'传统方式' 调用是行不通的. 注, conventional'传统方式' 调用 指的是如下面例子中 len() 跟 __le…

Caveats 说明 As of Java 7, functional programming in Java can only be approximated through awkward and verbose use of anonymous classes. This is expected to change in Java 8, but Guava is currently aimed at users of Java 5 and above. 在Java7中, 只能通过笨拙且啰嗦…

Accord.NET Framework是在AForge.NET项目的基础上封装和进一步开发而来.因为AForge.NET更注重与一些底层和广度,而Accord.NET Framework更注重与机器学习算法以及提供计算机视频.音频.信号处理以及统计应用相关的解决方案.该项目使用C#语言编写,项目主页:http://accord-framework.net/ 说明:该文章只是一个基本介绍,主要内容是翻译的官方文档和介绍,部分英文表述个人能力有限,不太熟悉,所以直接照搬原文,有比较确切的知道中文名…
