LabVIEW Class
A LabVIEW Class is a file with extension, *.lvclass. It is an XML file that stores information about the files owned by the library. The Project Explorer is used to view and edit these files. It is not recommended to edit the XML directly. The LabVIEW Class is a specialization of the LabVIEW Project Library but has extended behavior to contain data and support encapsulation and inheritance for Object-oriented programming.
