在Kotlin中，如何使一个属性只能在其类内进行变异？[副本]

Question

我在编程方面是新手，尤其是在科特林，如果我的问题太基础了，我很抱歉

class Person {

    var name = ""

    fun changeName(newName: String) {
        name = newName
    }


}

somePerson.name = "newNameIsNotAllowedHere"

class Person {

    val name = ""

    fun changeName(newName: String) {
        name = newName // can't assign new value because of val
    }


}

    private val mIsLoadingData = MutableLiveData<Boolean>()
    val isLoadingData : LiveData<Boolean>
        get() =  mIsLoadingData

公共吸血鬼和私人二传手：

class Person {

    var name: String = ""
        private set

}
