◆ GetConversationList() [1/2]

virtual void GetConversationList	(	uint64_t	nextSeq,
		uint32_t	count,
		V2TIMValueCallback< V2TIMConversationResult > *	callback
	)

pure virtual

1.3 Get the conversation list

Each conversation corresponds to a chat window. For example, a one-to-one chat or a chat group is a conversation.
Since there may be a large number of historical conversations, you are advised to call this API in query-by-page mode and pull 100 historical conversations per page at a time.
This API pulls locally cached conversations. If conversations on the server are updated, the SDK automatically synchronizes the updates internally and then notifies users via V2TIMConversationListener callback.
If all conversations are pulled, the value of the isFinished field in V2TIMConversationResult in the success callback is true.

Attention

Conversation sorting rules

For 5.5.892 and later versions, conversations on the conversion list obtained by this API are sorted by orderKey by default. The larger the orderKey value, the higher the order of the conversation.
For versions earlier than 5.5.892, conversations on the conversion list obtained by this API are sorted by "lastMessage -> timestamp" by default. The later the timestamp, the higher the order of the conversation.

Parameters

nextSeq	Pulling-by-page cursor. It is set to 0 when the information is pulled for the first time. The value of this field in the callback for the current paginated pulling is passed in for the next pull.
count	Number of conversations pulled per page. The value of this field cannot be too large; otherwise, the pulling speed is affected. We recommend that you pull 100 conversations per page.

When messages in a conversation are deleted from local storage, they are also deleted from the server.

◆ DeleteConversationList()

virtual void DeleteConversationList	(	const V2TIMStringVector &	conversationIDList,
		bool	clearMessage,
		V2TIMValueCallback< V2TIMConversationOperationResultVector > *	callback
	)

clearMessage	Whether to delete messages in the conversation; if this is set to false, the messages are retained; if this is set to true, the messages will be deleted from local storage and the server and cannot be recovered.

Attention: A maximum of 100 conversations are supported at a time.

		const V2TIMBuffer &	customData,
		V2TIMValueCallback< V2TIMConversationOperationResultVector > *	callback

◆ PinConversation()

virtual void PinConversation	(	const V2TIMString &	conversationID,
		bool	isPinned,
		V2TIMCallback *	callback
	)

pure virtual

1.11 Pin a conversion to the top (supported only in 5.3.425 and later versions)

Parameters

conversationID	Unique ID of a conversation. For one-to-one chats, the value format is String.format("c2c_%s", "userID"). For group chats, the value format is String.format("group_%s", "groupID").
isPinned	Whether to pin a conversation to the top

◆ MarkConversation()

virtual void MarkConversation	(	const V2TIMStringVector &	conversationIDList,
		uint64_t	markType,
		bool	enableMark,
		V2TIMValueCallback< V2TIMConversationOperationResultVector > *	callback
	)

pure virtual

1.12 Mark a conversation（supported only in Chat Premium 6.5 and later versions）

Parameters

conversationIDList	conversation list
markType	mark type of the conversation. For the valid values, see the V2TIMConversationMarkType definition.
enableMark	true：mark false：unmark

If existing marks do not meet your needs, you can customize extension marks. Extension marks need to meet the following two conditions:

1、Extended mark values must not conflict with existing mark values in V2TIIMConversationMarkType.

2、Extended mark values must be a 0x1LL << n (32 <= n < 64, that is, n must be greater than or equal to 32 and less than 64). For example, you can use the extension mark "0x1LL << 32" to mean "Windows online".

Attention: : The extension mark value cannot be set to 0x1 << 32. It must be set to 0x1LL << 32, which explicitly tells the compiler that it is a 64-bit integer constant.

◆ GetTotalUnreadMessageCount()

virtual void GetTotalUnreadMessageCount ( V2TIMValueCallback< uint64_t > * callback )

pure virtual

1.13 Get the total message unread count of all conversations (supported only in 5.3.425 and later versions)

Attention

After you call this API to obtain the total count of unread messages for all conversations, the newest value will be notified to you through the OnTotalUnreadMessageCountChanged callback when unread message count of any conversation changed.
The total unread message count excludes muted conversations (conversations whose message receiving option is V2TIM_NOT_RECEIVE_MESSAGE or V2TIM_RECEIVE_NOT_NOTIFY_MESSAGE or V2TIM_RECEIVE_NOT_NOTIFY_MESSAGE_EXCEPT_AT).

◆ GetUnreadMessageCountByFilter()

virtual void GetUnreadMessageCountByFilter	(	const V2TIMConversationListFilter &	filter,
		V2TIMValueCallback< uint64_t > *	callback
	)

pure virtual

1.14 Get the total message unread count in conversations by filter (supported only in 7.0 and later versions)

Parameters

filter conversation filter

Attention

The total unread message count excludes muted conversations (conversations whose message receiving option is V2TIM_NOT_RECEIVE_MESSAGE or V2TIM_RECEIVE_NOT_NOTIFY_MESSAGE or V2TIM_RECEIVE_NOT_NOTIFY_MESSAGE_EXCEPT_AT).

◆ SubscribeUnreadMessageCountByFilter()

virtual void SubscribeUnreadMessageCountByFilter ( const V2TIMConversationListFilter & filter )

pure virtual

1.15 Subscribe to changes in the total unread message count for specified conversations (supported only in 7.0 and later versions)

Attention

After you call this API, the newest value of total unread message count for conversations that match the filter parameter will be notified to you through the OnUnreadMessageCountChangedByFilter callback.

◆ UnsubscribeUnreadMessageCountByFilter()

virtual void UnsubscribeUnreadMessageCountByFilter ( const V2TIMConversationListFilter & filter )

pure virtual

1.16 Unsubscribe from changes in the total unread message count for specified conversations (supported only in 7.0 and later versions)

Parameters

filter conversation filter

		uint64_t	cleanTimestamp,
		uint64_t	cleanSequence,
		V2TIMCallback *	callback
	)

pure virtual

1.17 Clear unread messages of a conversation (supported only in 7.1 and later versions)

Parameters

conversationID	Unique ID of a conversation. For one-to-one chats, the value format is String.format("c2c_%s", "userID"). For group chats, the value format is String.format("group_%s", "groupID").
cleanTimestamp	The timestamp (seconds) for clearing unread messages (only valid for one-to-one chats). Unread messages before the timestamp will be cleared. If the value is 0, all unread messages of the specified conversation will be cleared, and the unread message count will be set to 0.
cleanSequence	The sequence for clearing unread messages (only valid for group chats). Unread messages before the specified message sequence will be cleared. If the value is 0, all unread messages of the specified conversation will be cleared, and the unread message count will be set to 0.

Attention

If you want to clear the unread messages of all a one-to-one conversation, set conversationID to "c2c", i.e., don't specify the userID.
If you want to clear the unread messages of all group conversations, set conversationID to "group", i.e., don't specify the groupID.
If you want to clear the unread messages of all conversations, set conversationID to "".
After the API is successfully called, you will receive the onConversationChanged callback that carries the latest unread message number of the corresponding conversation.
