inline

inline函数展开lambda,但是不展开函数引用.

kotlin:

funmain(args:Array){? ? println("Hello World!")varm =1;// Try adding program arguments via Run/Debug configuration.// Learn more about running applications: https://www.jetbrains.com/help/idea/running-applications.html.? test(args, ::test3)// test3()}privatefuntest3(i:Int){? ? println("test3 Program arguments:${1in3downTo1}")}privateinlinefuntest(args:Array, test3P: (Int)->Unit){valj =1println("Program arguments:${j}${args.joinToString()}")? ? test3P(j)}
