joinChatRoom

@Deprecated()
public abstract void joinChatRoom(String chatRoomId, int defMessageCount, OperationCallback callback)

Deprecated

Joins a chatroom.

If the chatroom does not exist, the SDK will create and join the chatroom. If it already exists, the SDK will directly join it. The number of historical messages to fetch after successfully joining the chatroom can be set via the `defMessageCount` parameter. -1 indicates no historical messages will be fetched, 0 indicates no special settings and the SDK's default settings will be used (default is to fetch 10 messages), and `defMessageCount` 0 < defMessageCount <= 50 specifies the number of messages to fetch, with a maximum of 50.

Deprecated

5.6.3

Parameters

chatRoomId

The ID of the chatroom.

defMessageCount

The number of messages to fetch when joining the chatroom. -1 means no messages will be fetched, 0 means 10 messages will be fetched, and the maximum is 50. (When joining the chatroom, the timestamp of the last local message will be passed, and messages after this timestamp will be fetched. For example: if there are 3 messages after this timestamp and `defMessageCount` is set to 10, only 3 messages will be fetched.)

callback

The status callback.
