The new Ruby Whois version will offer the ability to check whether a property is set using the standard
method? Ruby convention. This means, you no longer need to check whether a property is supported, get the property value and compare it to
a = Whois.query "google.it" a.created_on? # => true a = Whois.query "notregistered.it" a.created_on? # => false
Two important aspects to keep in mind. First, this method works only at answer level.
a = Whois.query "google.it" a.created_on? # => true a.parser.created_on? # => NoMethodError
Second, this method doesn't care whether the property is supported or not. It returns
false either if the property is not supported or the value is
a = Whois.query "notregistered.it" # created_on is a property supported # by .it TLD parser and empty for this # specific query a.created_on? # => false # domain_is is not a property supported # by .it TLD parser a.domain_id? # => false
