In Kotlin, functions are first-class citizens, so we can pass functions around or return them just like other normal types. However, the representation of these functions at runtime sometimes may cause a few limitations or performance complications. In this tutorial, first we’re going to enumer...

答:高阶函数! 只有高阶函数中才需要inline去做内联优化,普通函数并不需要,如果在普通函数强行加上inline,编辑器会立刻提醒: Expected performance impact from inlining is insignificant. Inlining works best for functions with parameters of functional types 意思是 内联对普通函数性能优化的预期影响是微不足道的。
The inline function is one of the default functions in the kotlin language that can be basically used to requesting the compiler to copy the inlined code at the calling place on the script. If the program is compiled using the compiler and it keeps the wrapper classes for each inline class...
[code lang=”kotlin”]inline fun lock<T>(lock: Lock, body: () -> T): T { // … }[/code] inline修饰符会影响函数本身和传递给该函数的 Lambda:它们都会在调用处内联。 内联会导致生成的代码量变大,但如果合理地利用(不要内联大函数),就会带来性能上的收益,尤其是在循环内的“超级多态(Mega...
也就是说加了crossinline 的函数如果直接将lambda参数作为另一个函数的返回值,这种情况是不被允许的。 下附参考链接 http://blog.csdn.net/u013009899/article/details/78584994 http://kotlinlang.org/docs/reference/inline-functions.html

as well as in the entry added to the changelog. Also IMO from a Kotlin user point of view, even without branch coverage the ability to see line coverage for inline functions is quite a significant improvement on its own - recall that JaCoCo was not reporting branch coverage at all till ve...
翻译说明: 原标题: Effective Kotlin: Consider inline modifier for higher-order functions 原文地址: blog.kotlin-academy.com 原文作者: Marcin Moskala 你或许已经注意到了所有集合操作的函数都是内联的(inline)。你是否问过自己它们为什么要这么定义呢? 例如,这是Kotlin标准库中的filter函数的简化版本的源码: ...
