Hi,
you should put your logic for computing the "result value" of a name into an
extension method.
Something like this:
coll.sortBy(name.resultValue)
def resultValue(String input) {
if (!input.contains(',')) {
return input
}
val inputParts = input.split(',')
var result = 0
for (s : inputParts) {
result = result + Integer.valueOf(s)
}
result.toString
}
