========================
|
|
|
|
* 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.
