CHAPTER 5  APPLYING SOME OBJECT ORIENTED DESIGN

Objects and object classes
An object is an entity that has a state and a defined set of operations which operate on that state. The state is represented as a set of object attributes. The operations associated with the object provide services to other objects (clients)[r]

expects a main() function to be defined. If we forget to provide one, our program will not run. The parameter list of a function is enclosed in parentheses and is placed after the name of the function. An empty parameter list, such as that of main(), indicates that the function accepts no parameters[r]

As depicted in Figure 8, during the simulation execution, the ON/OFF animation of the PLC input/output ports is displayed in parallel with the product flows. Input ports are located at the left side of a PLC, and output ports are located at[r]

Associations between actors and classes are indicated in use case diagrams,a relationship exists whenever an actor is involved with an interactiondescribed by a use case. Associations also exist between use cases in systemuse case models, a topic discussed in the following section, something thatdid[r]
