Hey, Ray. I think you are right. I found a type def named "attributes.ctl" in this lvclass. So, is it just a cluster? The icon shown as an object...( Actually, I did not use object before, is it similar to cluster?) The wire is different to cluster as well.
a lvclass is an object, as in Object Oriented Programming. The CS definition of a class, which an object is an instance of, is a set of data and the methods that operate on that data. In that respect a cluster is similar in that it can be viewed as the class data. OOP also brings other things to the table such as access scope and inheritance. Based on your questions I think this is your first exposure to OOP. I recommend you do some general reading to familiarize yourself with OOP in general. It is not a LabVIEW only concept. In fact, LabVIEW was rather late to the game in supporting OOP.
