若存在函数体,则函数体在->之后声明 在Kotlin中,有一个常见用法:如果一个函数的最后一个参数是函数类型,且传入的实参时λ表达式,则可以在圆括号之外给出这个λ表达式: lock(lock){sharedResource.operation()} 高阶函数的另一个形象的例子是map()函数: fun<T,R>List<T>.map(transform:(T)->R):List<R>{...
The elliptic anisotropy values based on different orders of multiparticle cumulants, v2{2k}, are measured up to the tenth order (k = 5) as functions of the collision centrality at a nucleon-nucleon center-of-mass energy of √ sNN = 5.02 TeV. The data were recorded by the CMS experiment ...
function body由大括号括起来的代码块组成。 1. Single expression functions: 只有一个表达式的函数 funconcat1(a:String,b:String)=a+bfunconcat2(a:String,b:String):String{returna+b}funisSuccess1():Boolean{returntry{true}catch(e:Exception){false}}funisSuccess2():Boolean=try{true}catch(e:Exceptio...
This example shows how to createMaybetype which represents optional value. 1. Define effect algebra First we need to define aMaybealgebra which means we need to define signature creation and eliminationMaybevalues.Maybehas two constructors, so to deconstruct we need two functions, handle each case...
This article is for anyone who is curious about the higher-order functions and lambdas in Kotlin but has no idea what they are exactly.
