TRTCSwitchRoomParam

Constructor

This parameter is used for the room switch API switchRoom, which can quickly switch a user from one room to another.

Name	Type	Description
`roomId`	Number	`required` numeric room ID, which is optional. Users in the same room can see one another and make audio/video calls. [Note] either `roomId` or `strRoomId` must be entered. If both are entered, `roomId` will be 0(zero).
`strRoomId`	String	`required` string-type room ID, which is optional. Users in the same room can see one another and make audio/video calls.
`userSig`	String	`required` user signature, which is optional. It is the authentication signature corresponding to the current `userId` and acts as the login password. If you don't specify the newly calculated `userSig` during room switch, the SDK will continue to use the `userSig` you specified during room entry (enterRoom). This requires you to ensure that the old `userSig` is still within the validity period allowed by the signature at the moment of room switch; otherwise, room switch will fail. For the calculation method, please see UserSig.
`privateMapKey`	String	`required` permission credential used for permission control, which is optional. If you want only users with the specified `userId` values to enter a room, you need to use `privateMapKey` to restrict the permission. We recommend you use this parameter only if you have high security requirements. For more information, please see Enabling Advanced Permission Control.
