FSM은 광범위하게 사용되는 개념이다. 뭔가 상태가 존재하고, 그 각각의 상태에 따라 다른 처리를 해줘야한다면 FSM을 쓸 수 있다고 보면 된다.

뭔가 깔끔하고, 제너릭한 걸 만들어야 하는데…

• HierarchicalStateMachine
• StackBasedStateMachine – aka. PushDownAutomata

• Finite State Machines (FSM)

• Object-oriented implementation of state-based logic
  This paper addresses the problem of merging object-oriented and automaton-based programming technologies. There are two major questions: “how to integrate an automaton into an object-oriented system” and “how to implement an automaton in the object-oriented fashion”.

• CHSM
  CHSM is a language system for specifying concurrent, hierarchical, finite state machines (an implementation of “statecharts”) to model and control reactive systems.
• OMAC Finite State Machine (FSM) library
  The OMAC Finite State Machine (FSM) library is a free, with source-code, object-oriented Visual C++ class library for use in coding states, events, actions, transitions, and conditions necessary in programming and executing finite state machine behavior.
