| -------------- | -------------------------------------------------------------------------------- |
| Unknown        | 状态未知。                                                                            |
| Any            | 忽略会话可见性筛选器。                                                                      |
| PrivateSession | 会话是私密的，对不在会话中的玩家不可见。尝试加入将导致服务返回 HTTP\_E\_STATUS\_FORBIDDEN (403)。                |
| Visible        | 会话对不在会话中的玩家可见，但会话对他们是只读的，他们无法加入。尝试加入将导致服务返回 HTTP\_E\_STATUS\_BAD\_REQUEST (400)。 |
| Full           | 会话已满，任何人都无法加入。尝试加入将导致服务返回 HTTP\_E\_STATUS\_BAD\_REQUEST (400)。                   |
