Check if value in Scala Enumeration exists in an Array of Strings

Question

I have an enumeration like this:

object VersionTokens extends Enumeration {
  type VersionTokens = Value

  val ALL = Value("ALL")
  val CURRENT = Value("CURRENT")
}

Is there a way to check if any of the values in the enumeration exists in an array of strings?

pseudo code:

val versions = Array("CURRENT", "SOMETHING ELSE")
if(versions.contains(VersionTokens)) true
else false

// should return true since "CURRENT exists in the enumeration

You can, for example, check if the value set of your enumeration intersects your array :

VersionTokens.values.map(_.toString).toArray.intersect(versions).nonEmpty

or, less readable but faster:

VersionTokens.values.map(_.toString).toArray.exists(versions.contains)
