kotlin - 在kotlin中我可以在一行中初始化一个对象并设置参数

Question

类别:

class CameraBrandDto(override val id: Long = 0, override var dateCreated: Date = Date(), override var dateUpdated: Date = Date()) : DataTransportObject {
    override var clazz = this.javaClass.simpleName.replace("Dto", "")

    @NotBlank
    @Size(max = 13)
    var name: String = ""

    var models: MutableSet<DtoMin> = mutableSetOf(DtoMin(0, "UNDEFINED", "UNDEFINED", Date(), Date()))

}

我想用一行完成这个任务

val axisDto  = CameraBrandDto()
axisDto.name = "AXIS"

这可能吗？？？

Answer 1

可以，使用标准库函数.apply { ... }即可，执行 the lambda with receiver对象并返回该对象:

val axisDto = CameraBrandDto().apply { name = "AXIS" }
