defineClass() 这个函数返回一个特殊的 cookie，而不是实际的类字节，不能修改字节
You can define theuserdataargument in thissetDrawCallbackfunction as a class in the library. void setDrawCallback(const String& winname, OpenGlDrawCallback onOpenGlDraw, void* userdata = 0) void on_opengl(void* param) { cv::ogl::Texture2D* backgroundTex = (cv::ogl::Texture2D*)param;...
1、尽量用const和inline而不用#define 这个条款最好称为：“尽量用编译器而不用预处理”，因为#define经常被认为好象不是语言本身的一部分。这是问题之一。2、再看下面的语句：define ASPECT_RATIO 1.653 编译器会永远也看不到ASPECT_RATIO这个符号名，因为在源码进入编译器之前，它会被预处理程...

Javascript是一种基于对象(object-based)的语言,你遇到的所有东西几乎都是对象。但是,它又不是一种真正的面向对象编程(OOP)语言,因为它的语法中没有class(类)。 那么,如果我们要把"属性"(property)和"方法"(method),封装成一个对象,甚至要从原型对象生成一个实例对象,我们应该怎么做呢?
