Example
The following abstract defines an EmailAddress type based on the String type which will use a regular expression to validate the passed argument as an e-mail address. If the address isn't valid, an exception will be thrown.
abstract EmailAddress(String) {
static var ereg = ~/^[\w-\.]{2,}@[\w-\.]{2,}\.[a-z]{2,6}$/i;
inline public function new(address:String) {
if (!ereg.match(address)) throw "EmailAddress "$address" is invalid";
this = address.toLowerCase();
}
}
Use the abstract as follows.
var emailGood = new EmailAddress("[email protected]");
var emailBad = new EmailAddress("john.doe.com");
