Kotlin Annotation IntDef

Question

I have this code sample:

class MeasureTextView: TextView {
    constructor(context: Context?) : super(context)
    constructor(context: Context?, attrs: Attr         


        

Answer 1

Strange thing, but this question comes in search before the same with right answer

Copying it here:

import android.support.annotation.IntDef
public class Test {

    companion object {

         @IntDef(SLOW, NORMAL, FAST)
         @Retention(AnnotationRetention.SOURCE)
         annotation class Speed

         const val SLOW = 0
         const val NORMAL = 1
         const val FAST = 2
    }

    @Speed
    private var speed: Int=SLOW

    public fun setSpeed(@Speed speed: Int) {
        this.speed = speed
    }
}
