Accessing Object Attributes · Vending Machine object attributes shown in the Information Model may be accessed from any VM state Process Model · Dispenser object attributes may be accessed from any VM state Process Model using the relationship R 2 · Object instances must be identified to access attributes: Vending_Machine(1). Total_Number_Of_Quarters_Available or Vending_Machine(1). Current_State or Dispenser(33). Snack_Selection_Number · Setting an attribute: Vending_Machine(1). Total_Number_Of_Quarters_Available = 5 · Printing an attribute: print Vending_Machine(1). Current_State Mississippi State University Page 10 10/31/2020

Exists is used to test if an object instance exists If (Exists (Dispenser(33))) { // Dispenser(33) exists // Delete Dispenser(33) // <delete Dispenser(33)> } If (!Exists (Dispenser(33))) { // Dispenser(33) does not exists // Create Dispenser(33) and initialize its attributes // <create Dispenser(33)…> } Mississippi State University Page 15 10/31/2020
Include C language as needed · And that’s everything required to complete the Process Model for your most interesting object · Think about what you need to do, then express it using pseudo-code Mississippi State University Page 16 10/31/2020
