字段

修饰符和类型	字段	说明
final byte	cmd	切换命令
static final byte	CMD_NONE
static final byte	CMD_REDO
static final byte	CMD_UNDO
static final byte	DELAY_NONE	不延迟 1.delayArg为当前状态要设置的结果，大于0有效 -- 用于更好的支持FSM。
static final byte	DELAY_WHEN_COMPLETED	在当前子节点完成的时候切换 1.其它延迟模式也会在当前状态完成时触发； 2.通常用于状态主动退出时，可避免自身进入被取消状态 -- 先调用changeState，然后setSuccess;
final int	delayArg	延迟参数
