Introduction

TinyFSM is a simple finite state machine library for C++, designed for optimal performance and low memory footprint. This makes it ideal for real-time operating systems. The concept is very simple, allowing the programmer to fully understand what is happening behind the scenes. It provides a straightforward way of mapping your state machine charts into source code.

TinyFSM basically wraps event dispatching into function calls, making event dispatching equally fast to calling (or even inlining) a function. Even in the worst case, dispatching leads to nothing more than a single vtable lookup and function call!

Key Features

• Entry/exit actions
• Event actions
• Transition functions
• Transition conditions
• Event payload (classes)
• Inheritance of states and action functions

TinyFSM benefits from the C++11 template metaprogramming features like variadic templates, and does not depend on RTTI, exceptions or any external library.
