或者,我们可以将变量标记为翻译单元局部(它不会被导出到对象文件之外)。为此,我们将使用static关键字,如下所示: chapter06/04-odr-success/shared.h 代码语言:javascript 代码运行次数:0 运行 复制 static int i; 所有其他文件都将保持不变,与原始示例一样,链接仍然成功。这当然意味着前面的代码中的变量为每个翻译...

A TEST_METHOD returns void. To produce a test result, use the static methods in the Assert class to test actual results against expected results. In the following example, assume MyClass has a constructor that takes a std::string. This example shows how you can test that the constructor in...
An Objective-C class method very much requires an instance that is the target of the method invocation. That is, it requires an instance of the metaclass that describes the class object being invoked. Unlike static methods, Objective-C's class methods can be inherited (which, in combination w...
public new static void M() { Console.WriteLine("call in class D"); } } public class Ewhere T : C { public static void N() { T.M(); } } 代码是错误的,不允许一个instance来call一个static method。如果你编译的话,会提示: Error 2 'T' is a 'type parameter', which is not valid ...

clang -rewrite-objc MyClass.m 好吧,我们得到了一个3M大小,10w多行的.cpp文件(这绝对是Apple值得吐槽的一点),我们忽略掉所有和我们无关的东西,在文件的最后,我们找到了如下代码片段: staticstruct/*_method_list_t*/ {unsignedintentsize;// sizeof(struct _objc_method)unsignedintmethod_count;struct_objc...
