实际上定义了一个隐式的类类型转换(implicit class-type conversion),将参数类型转换为类类型,也就是将int类型转换为A, 所以在调用print_A(5)时, 首先调用转换构造函数A(int k)将int k 转换为了一个临时的A类型的变量。

implicitclassSayhiImpl(ivalue:Int){valvalue:Int=ivaluedefsayhi=println(s"Hi $value!")}123.sayhi//合法 隐式类就是在类定义前加一个implicit关键字,这表示它的构造函数是一个隐式转换函数,能够将参数的类型转换成自己的类型,在这里就是构造函数SayhiImpl(ivalue:Int)定义了Int到SayhiImpl的隐式转换。
MATLAB first tries to call a converter method. If no converter method is found, it calls the constructor forClassA. The concatenation statement is equivalent to: C = [A,ClassA(B)] If the call to theClassAconstructor fails to convertBtoClassA, MATLAB issues an error. If the conversion su...

Scala 中的 implicit 关键字,除了能够加在 class 之前作为一个类的隐式转换之外,见:Scala 进阶(2)—— implicit 用法:隐式转换, 还能够加在参数之前,定义一个隐式参数。 2. 柯里化 隐式参数的应用是基于一个柯里化的函数定义,所以先简单地介绍一下柯里化函数。
