15.7 Summary

In this chapter, we covered the following:

• We discussed the goals of the airport application: to predict the arrival time and gate of an incoming aircraft, and to describe the entire path that an incoming aircraft will take, including the time it is expected to be at each point.

• We discussed the design of the airport application classes, and the operations to be performed on instances of the classes, including the vehicle-container protocol.

• We discussed how the time, angle, sorted sequence, and testing libraries interact with the main airport application library.

In Chapter 16, Definition of a New Collection, we implement sorted sequences. In Chapter 17, The Airport Application, we implement the airport application.
