static methods

• throw_if_nil() throw an ArgumentException if the given value is nil
• throw_if_empty() throw an ArgumentException if the given value returns true to empty? (which nil does)
• throw_if_nil_or_empty() throw an ArgumentException if the given value is nil or returns true to empty?
• throw_if_nil_or_whitespace() throw an ArgumentException if the given value is nil, returns true to empty? or is a string made up of entirely whitespace characters. This will also throw an ArgumentException itself if the given value is neither nil nor a String.
