为了使 Kotlin 接口实现更易于维护,您可以遵循以下最佳实践:
interface MyInterface {
fun doSomething()
}
class MyClass : MyInterface {
override fun doSomething() {
// 实现具体逻辑
}
}
interface MyInterface {
fun doSomething()
}
fun MyInterface.doAnotherThing() {
// 添加新方法
}
class MyClass : MyInterface {
override fun doSomething() {
// 实现具体逻辑
}
}
fun main() {
val myClass = MyClass()
myClass.doSomething()
myClass.doAnotherThing()
}
interface MyInterface {
fun doSomething()
@Default
fun doAnotherThing(): String {
return "Default implementation"
}
}
class MyClass : MyInterface {
override fun doSomething() {
// 实现具体逻辑
}
}
fun main() {
val myClass = MyClass()
myClass.doSomething()
println(myClass.doAnotherThing()) // 输出 "Default implementation"
}
interface MyInterface {
var myProperty: String
@get
@set
fun propDelegate(block: (String) -> String)
}
class MyClass : MyInterface {
private var _myProperty = ""
override var myProperty: String
get() = _myProperty
set(value) {
_myProperty = block(value)
}
override fun propDelegate(block: (String) -> String) {
// 实现属性委托逻辑
}
}
fun main() {
val myClass = MyClass()
myClass.myProperty = "Hello"
println(myClass.myProperty) // 输出 "Hello"
}
遵循这些最佳实践可以帮助您创建更易于维护的 Kotlin 接口实现。
