First off, you should use data types with your class and then you won't
have to check--the compile won't even succeed unless you've got the right
data type.
class foo (
Integer $subsetting,
) {
# $subsetting is guaranteed to be numeric here
....
}
Second, you can use the is_a
<https://forge.puppet.com/puppetlabs/stdlib#is_a> function, or the ~=
equality matcher.
