在Kotlin多继承架构中，可以使用委托模式实现Builder模式。例如：

interface Builder { fun build(): T }

open class Person(val name: String, val age: Int)

class Employee(name: String, age: Int, val company: String) : Person(name, age) { class Builder : Builder { private var name = "" private var age = 0 private var company = ""

    fun name(name: String) = apply { this.name = name }
    fun age(age: Int) = apply { this.age = age }
    fun company(company: String) = apply { this.company = company }

    override fun build() = Employee(name, age, company)
}

}

fun main() { val employee = Employee.Builder() .name("John") .age(30) .company("ACME") .build()

println("Employee: ${employee.name} (${employee.age}), works at ${employee.company}")

}

在这个例子中，我们定义了Builder接口，并将其实现用于构建Employee对象。每个属性都有一个对应的builder方法，可以链式调用。最后，我们调用build方法以获取最终的对象。
