I have a WrappedArray value of type Any. How do I convert to Array.
For Ex:
val flds = valArr(0)(2)
flds: Any = WrappedArray(F1,F2,F3,F4,F5)
I tried converting flds to String Array..
val flds = valArr(0)(2).toArray
But I got the below error
<console>:41: error: value toArray is not a member of Any
How do I convert..? I just want to loop through wrappedArray, But I didnt know how to do that.. Thats why I am trying to convert it to Array and loop through it.
This is how to get WrappedArray from Array and vice versa:
val warr: WrappedArray[Int] = WrappedArray.make(Array(1, 2, 3))
val arr: Array[Int] = warr.array
or
val warr: WrappedArray[Int] = Array(1, 2, 3) // implicit conversion
val arr: Array[Int] = warr.array
Starting with a WrappedArray[Any]
val warr: WrappedArray[Any] = WrappedArray.make(Array(1, 2, 3))
I can get to an Array[Int] this way:
val arr: Array[Int] = warr.toArray.map(_.asInstanceOf[Int])
First you need to tell Scala that your WrappedArray is a WrappedArray, so
import scala.collection.mutable.WrappedArray
val warr = flds.asInstanceOf[WrappedArray[T]]
where T is the type of the array contents. Afterwards you will have all the methods of WrappedArray available, e.g. warr.toArray.
