并发状态机会影响子状态的调用次数

[Momo Cuki]

为什么我测试下来，并发状态机会影响调用的次数，发送一次事件，结果转换方法被调用好多次。

 测试结果 如下：

开始测试状态机事件

开始进入停止状态

onSuspendService from=InitRobot to=SuspendService   event=initerror.event

开始进入初始北状态

onInitRobot from=SuspendService to=InitRobot   event=reset.event

去掉并发状态，同时启动水位、广告、主 状态机

onRobot from=InitRobot to=Robot   event=initcomplete.event

开始进入低水位状态

onLowWater from=NormalWater to=LowWater   event=lowwater.event

开始进入播放广告状态

onPlayAd from=IdleAd to=PlayAd   event=havead.event

开始进入暂停播放广告状态

onPauseAd from=PlayAd to=PauseAd   event=pausead.event

开始进入服务状态

onInService from=InIdle to=InService   event=inservice.event

开始进入下班状态

onWorkOff from=InService to=WorkOff   event=workoff.event

开始进入播放广告状态

onPlayAd from=PauseAd to=PlayAd   event=palyad.event

开始进入暂停状态

onPauseService from=Work to=PauseService   event=work2pauseservice.event

onPauseService from=Work to=PauseService   event=work2pauseservice.event

开始进入无广告状态

onIdleAd from=PlayAd to=IdleAd   event=noad.event

开始进入正常水位状态

onNormalWater from=LowWater to=NormalWater   event=normalwater.event

开始进入高水位状态

onHighWater from=NormalWater to=HighWater   event=highwater.event

开始进入恢复暂停状态

onWork from=PauseService to=Work   event=pauseservice.event

onWork from=PauseService to=Work   event=pauseservice.event

onWork from=PauseService to=Work   event=pauseservice.event
