Applied C++: Practical Techniques for Building Better Software

Chapter 3. Design Techniques

IN THIS CHAPTER

• C++ Concepts

• Memory Allocation Object

• Singleton Object

• Reference Counting

• Template Primer

• Handles and Rep objects

• Prototyping Strategy

• Image Framework Concepts

• Image Object (Prototype 1)

• Templated Image Object (Prototype 2)

• Image Storage (Prototype 3)

In this chapter, we lay the groundwork for extending our digital imaging framework. We begin by designing a memory allocation object, and then continue with a templates primer that provides a road map to subtleties of templates and their use. Finally, we apply C++ constructs to specific aspects of the design by creating detailed prototypes, and discussing the advantages and disadvantages of each technique.

Memory Allocation
