|
|
Keep it Simple
|
||
|
|
--------------
|
||
|
|
|
||
|
|
By design, TinyFSM implements only the very basics needed for
|
||
|
|
designing state machines. For many people, it is important to know
|
||
|
|
what a library is doing when making a decision for a specific library.
|
||
|
|
|

|
|
|
||
|
|
State Definition
|
||
|
|
----------------
|
||
|
|
|
||
|
|
States are derived classes from a base FSM state, providing react()
|
||
|
|
functions for every event, as well as entry() and exit() functions.
|
||
|
|
|
||
|
|
|
||
|
|
Event Dispatching
|
||
|
|
-----------------
|
||
|
|
|
||
|
|
TinyFSM does not hold state/event function tables like most other
|
||
|
|
state machine processors do. Instead, it keeps a pointer to the
|
||
|
|
current state (having the type of the state machine base
|
||
|
|
class). Dispatching an event simply calls the react() function of the
|
||
|
|
current state, with the event class as argument. This results in a
|
||
|
|
single vtable lookup and a function call, which is very efficient!
|
||
|
|
|
||
|
|
Event dispatching on an FsmList<> are simply dispatch() calls to all
|
||
|
|
state machines in the list.
|
||
|
|
|
||
|
|
|
||
|
|
Header-Only Library
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
The TinyFSM library consist entirely of header files containing
|
||
|
|
templates, and requires no separately-compiled library binaries or
|
||
|
|
special treatment when linking.
