func 里面的变量 x 是一个新变量,只不过与外层 x 重名了(variable redeclaration),此时里层 x 的作用域仅限于 func {} block,而外层 x 的作用域则是 main
init(_ variable:String) { self.init() } //convenience init() { self.init() } //error: redeclaration
case 0: let foo; break; case 1: let foo; // TypeError for redeclaration
parameters // 在这种情况下const修饰对于来说限制实参传递是没有用的 void Print(short) { //... } void Print(const short) // redeclaration
RACSubscriber> - (instancetype)init __attribute__((unavailable("Instantiate a RACChannel instead"))); // Redeclaration
方法定义锁定,如以下示例所示: 示例 111.在 CRUD 方法上定义锁元数据 interface UserRepository extends Repository<User, Long> { // Redeclaration
down option while clicking Product in the Xcode menu shows the Clean Build Folder…option 三、Invalid redeclaration
struct Demo { @State var name = "fat" var _name:String = "ds" // invalid redeclaration of synthesized
{ SAT, SUN, }DAY; */ /* // 错误2,枚举成员重名,编译时报错:redeclaration
{ SAT, SUN, }DAY; */ /* // 错误2,枚举成员重名,编译时报错:redeclaration
pi := 3.14156 # Redeclaration error because 'pi' already declared above.
let x = 1; switch(x) { case 0: let foo; break; case 1: let foo; // SyntaxError for redeclaration
o ifswitch 2.03.if.switch.cpp: In function \u2018int main()\u2019: 2.03.if.switch.cpp:23:38: error: redeclaration
这里确实不允许两个函数通过他们的效果词来做区分,比如不能定义两个仅仅只有throws不同的函数: // error: redeclaration of function `doSomethingElse
file.h:47: previous declaration of 'item'Explanation and Fix (解释和修复)The programmer made an erroneous redeclaration
workday{MON, // MON = 1;TUE,WEN,THU,FRI,}DAY;typedef enum weekend{SAT,SUN,}DAY;*// /错误2,枚举成员重名,编译时报错:redeclaration
