LVCLASS File Extension
The LVCLASS File Extension (*.lvclass), or LabVIEW Class Library, is a special form of LabVIEW Project Library file that defines a new data type. LabVIEW classes define data associated with an object, as well as the methods that define the actions you can perform on the data. The benefits of encapsulation and inheritance allow you to create modular code that is easy to change without affecting code throughout the application. See LabVIEW Classes.
