这是一个条件迁移。
第三个迁移，从gate—另一个条件迁移—指向BookRoom活动，这时所需类型的房间是可入住的。
The third transition from the gate - another conditional transition - points to the BookRoom activity, in case the required type of room is available.
正如您所猜想的，您还必须设置其他迁移的条件。
As you might have guessed, you also must set a condition for the other transition.
