Problem: The hardest part of creating a State Machine is to differentiate between possible states in the state diagram. For example, in the Coke Machine state diagram (Fig.4), we could have had 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 cent states rather than having a “wait ...
You can use the state machine design pattern to implement decision making algorithms where a set of distinguishable states exists.
状态模式(State Design Pattern) 状态模式一般用来实现状态机,而状态机常用在游戏、工作流引擎等系统开发中。不过,状态机的实现方式有多种,除了状态模式,比较常用的还有分支逻辑法和查表法。 什么是有限状态机? 有限状态机,英文翻译是 Finite State Machine,缩写为 FSM,简称为状态机。 状态机有 3 个组成部分:状态...

This paper presents a new object-oriented design pattern — State Machine design pattern. This pattern extends capabilities of State design pattern. These patterns allow an object to alter its behavior when its internal state changes. Introduced event-driven approach loosens coupling. Thus automata co...

The State pattern allows an object to change its behavior when its internal state changes. This pattern can be observed in a vending machine. Vending machines have states based on the inventory, amount of currency deposited, the ability to make change, the item selected, etc. When currency is...
In that case, you can make a singlestaticinstance. Even if you have a bunch of FSMs all going at the same time in that same state, they can all point to thesame instancesince it has nothing machine-specific about it. This is theFlyweightpattern. ...
The figure below describes the state transition diagram for an active standby pair. The design here assumes that the active and standby are being managed by an external entity. The different states for the state machine are Active, Standby, Suspect and Failed. The input messages to be handled ...
