My program receives a scala map, the requirements is to validate this map (key-value pairs). Ex: validate a key value, convert its type from string to int etc. In a rare case, we update the key as well before passing the map to the down layer. Its not always required to update this map , but only when we detect that there are any unsupported keys or values. I'm doing some thing like this:
private def updateMap ( parameters: Map[String, String]): Map[String, String] = {
parameters.map{
case(k,v) => k match { case "checkPool" =>
(k, (if (k.contains("checkPool"))
v match {
case "1" => "true"
case _ => "false"
}
else v))
case "Newheader" => (k.replace("Newheader","header"),v)
case _ =>(k,v)
}
case _ => ("","")
}
} Like this the code increases for doing the validation and converting the keys/values to supported ones. Is there a cleaner way of doing this validation in Scala for a map?
