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.
