This chapter applies a different programming paradigm to G: Object-Oriented Programming(OOP). New languages like Java and its use on the Internet have createda lot of interest in this programming paradigm. This chapter explains the conceptsthat make object-oriented programming work, and applies them to programming inLabVIEW.This chapter begins with definitions of objects and classes. These are the fundamentalbuilding blocks of OOP. Key definitions that define OOP are then presentedwhich give a foundation for programmers to view applications in terms of theirconstituent objects.Once the basics of OOP are described, the first stage of objects is presented--object analysis. Fundamentally, the beginning of the design is to identify the objectsof the system. Section 10.4 discusses Object Design, the process by which methodsand properties are specified. The interaction of objects is also defined in the designphase. The third and last phase is the Object Programming phase. This is where thecode to implement the methods and properties is performed.This type of structuring seems foreign or even backward to many programmerswith experience in structured languages such as LabVIEW. Object-oriented is howprogramming is currently being taught to computer science and engineering studentsaround the world. A significant amount of effort has been put into the design of aprocess to produce high-quality software. This section introduces this type of philosophyto LabVIEW graphical programming.
