Re: [rules-users] How to use type-safe enums in rule condition
That rule would work if you added a “name” property to Country.
As a general tip on working with countries, always work with their ISO codes, not their
names.
http://en.wikipedia.org/wiki/ISO_3166-1
… ideally the 2-char codes, which are much more commonly used than the 3-char codes.
Feel free to steal this:
https://github.com/gratiartis/sctrcd-payment-validation-web/blob/master/s...
… which sets up all countries with ISO codes and full-text names as enums. Or at least all
countries which were included in the ISO spec at the time of writing.
Grab it while you can - I’m in the middle of refactoring it into a JPA entity. :)

Hello,
I would like to use type-safe enums in my rules. At the moment I have
situation like this:
public class Country {
private String name;
// getter/setters
}
rule "Country"
when
Country ( name == "USA" )
then
DO SOMETHING
end
I would like to have something like this:
public enum Country {
USA ()
// list of all countries in the world
}
and in the rule I would like to do this:
rule "Country"
when
Country ( name == Country.USA )
then
DO SOMETHING
end
Is that possible?
Thanks in advance for your help.
