| What's In This Directory |
| ======================== |
| |
| * player1.cpp - this is exactly what's covered in C++ Template |
| Metaprogramming (http://www.boost-consulting.com/mplbook); in fact, |
| it was auto-extracted from the examples as shown in the book. The |
| state machine framework and its use are together in one .cpp file; |
| normally they would be separated. You can think of the framework as |
| ending with the definition of the generate_dispatcher class |
| template. |
| |
| You can ignore the typedef called "dummy;" that was included in order to |
| test an intermediate example that appears in the book. |
| |
| * player2.cpp - this example demonstrates that the abstraction of the |
| framework is complete by replacing its implementation with one that |
| dispatches using O(1) table lookups, while still using the same code |
| to describe the particular FSM. Look at this one if you want to see |
| how to generate a static lookup table that's initialized at dynamic |
| initialization time. |
| |
| * player.cpp, state_machine.hpp - This example predates the book, and |
| is more sophisticated in some ways than what we cover in the other |
| examples. In particular, it supports state invariants, and it |
| maintains an internal event queue, which requires an additional |
| layer of runtime dispatching to sort out the next event to be |
| processed. |
