case class CountryCodeA3 extends Product with Serializable

A CountryCodeA3 represents an ISO 3166 alpha-3 country code.

Details of the ISO 3166-1 alpha 3 codes can be found here: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-3

Pattern Matching

Pattern matching is supported as illustrated by the following examples,

"JAM" match {
case CountryCodeA3(code) => code  // "JAM"
case _ => None
}

Invalid country codes will not be matched.

"JA" match {
case CountryCodeA3(code) => code
case _ => None  // None
}
Implicit Conversions

An implicit conversion is provided which allows an instance of CountryCodeA3 to be used when a String is required.

def logCode(code: String) = println(s"code: $code")

val cc = CountryCodeA3.opt("TKL").get
logCode(cc) // "code: TKL"

An implicit conversion to the unconstrained version of this class is also available.
