状态对象、状态转移表、状态条件表、状态行为表

class stateMachine {
    //状态机名称
    static stateMachineName = ''
    // 当前状态
    static currentState = ''
    // 状态对象(状态集合)
    static StateTable:{
        // 索引签名
        [key:string]:number
    } = {}
    // 状态条件表(事件集合)
    static COND = {}
    // 状态转移表
    static StateTransitionTable:any = []
    // 状态行为表
    static StateActionTable:{
        // 索引签名
        [key:string]:string
    } = {}
    // 根据当前状态和事件获取下一个状态
    static get_state_transition(condition:string, now_statu = stateMachine.currentState):string {
        return stateMachine.StateTransitionTable[stateMachine.StateTable[now_statu]][condition];
    }
    // 执行迁移状态,会修改现在状态,并执行迁移函数
    static move_status(statu:string) :string{
        let callback = stateMachine.StateActionTable[statu];
        stateMachine.currentState = statu; //改状态 
        if (callback == undefined) {
            throw ('无处理函数')
        }
        // 返回执行动作
        return callback;
    }
}

测试

// 测试
stateMachine.stateMachineName = 'test stateMachine'
stateMachine.currentState = 'STA_START'
stateMachine.StateTable = {
    STA_START: 0,
    STA_U1: 1,
    STA_U2: 2,
    STA_L1: 3,
    STA_END: 4,
    STA_ERROR: 5,
}
stateMachine.COND = {
    upper: 0,
    lower: 1,
    end: 2,
}
stateMachine.StateTransitionTable = [
    //事件: upper,lower,end
    ['STA_U1', 'STA_L1', 'STA_END'], //START
    ['STA_U2', 'STA_L1', 'STA_END'], //U1
    ['STA_U2', 'STA_L1', 'STA_END'], //U2
    ['STA_U1', 'STA_L1', 'STA_END'], //L1

stateMachine.StateActionTable = {
    'STA_U1': 'do_u1',
    'STA_U2': 'do_u2',
    'STA_L1': 'do_l1',
}

// 测试部分
console.log(stateMachine)
console.log(stateMachine.currentState)
stateMachine.move_status(stateMachine.get_state_transition('1'))
console.log(stateMachine.currentState)
stateMachine.move_status(stateMachine.get_state_transition('0'))
console.log(stateMachine.currentState)
stateMachine.move_status(stateMachine.get_state_transition('0'))
console.log(stateMachine.currentState)
