在Kotlin 中,使用顶层方法(Top-level functions)来取代伴生工厂方法也很常见,比如listOf,setOf,mapOf。 库的设计者也经常提供顶层方法来创建实例。举个例子,Android 开发中,传统的方法是使用静态方法去创建ActivityIntent: // Java class MainActivity extends
* Only the top-level functions can have a contract for now. * * @param builder the lambda where the contract of a function is described with the help of the [ContractBuilder] members. * */@ContractsDsl @ExperimentalContracts @InlineOnly @SinceKotlin("1.3")@Suppress("UNUSED_PARAMETER")publi...
Functions can be top-level elements (i.e., there is no need to put everything inside a class) Functions are first-class citizens: they can be passed around just like any other type and used as argument of functions. Lambda (i.e., anonymous functions) are greatly supported by the standa...
Kotlin has had top-level functions and properties from day one. They are very convenient in many cases: from basic utilities to extensions for standard APIs. But Kotlin code is not the only client, and today I’m going to explain how we are planning to improve on the Java interop when i...

These top-level functions can be mocked using mockkStatic. You just need to import the function and pass a reference as the argument:import com.cars.buildCar val testCar = Car() mockkStatic(::buildCar) every { buildCar() } returns testCar assertEquals(testCar, buildCar()) verify { ...

Placing multiple declarations (classes, top-level functions, or properties) in the same Kotlin source file is encouraged as long as these declarations are closely related to each other semantically, and the file size remains reasonable (does not exceed a few hundred lines). ...
