ABSTRACT
In this chapter, I present concrete implementations of the QF design described in the previous chapter. The primary goal is to fill in the missing platform-dependent pieces of the framework so that you have the complete code ready to use in your applications. This chapter approaches the dilemma — which platform to choose — by describing not one but three implementations of the QF on different platforms. I have chosen diverse platforms to demonstrate how to adapt the QF to a wide range of applications because my secondary goal in this chapter is to show you how to port the QF to the environment of your choice.
