ChannelListDataHandler

All Implemented Interfaces:

ai.nexconn.chatui.base.interfaces.OnPagedDataLoader
```
public class ChannelListDataHandler
extends MultiDataHandler implements OnPagedDataLoader
                    
```
Core data handler for the channel list
Responsible for channel data fetching, filtering, sorting, deduplication, and UI model management. Implements OnPagedDataLoader to support load-more pagination.
Data loading has two paths:
- refresh — initial load or event-driven refresh, resets pagination (auto-coalesces rapid calls)
- loadNext — paginated load-more
Since:

5.10.4

- Method Detail
  - refresh
```
 void refresh()
```
    Refreshes the channel list. Rapid successive calls are auto-coalesced.
  - refresh
```
 void refresh(long delayMs)
```
    Refreshes the channel list with a custom delay.
    If delay is non-positive, falls back to the default coalescing window.
  - doUpdate
```
 void doUpdate(List<BaseChannel> channels)
```
  - updateByChannel
```
 void updateByChannel(BaseChannel channel)
```
    Updates a single channel (from event callback)
  - findConversationFromList
```
 BaseUiChannel findConversationFromList(ChannelType type, String channelId)
```
  - refreshConversationList
```
 void refreshConversationList()
```
  - isSupported
```
 boolean isSupported(ChannelType type)
```
  - loadNext
```
 void loadNext(OnDataChangeListener<Boolean> listener)
```
    Loads the next page of data.
    
    Parameters:
    
    listener - the load completion listener
  - hasNext
```
 boolean hasNext()
```
    Returns whether there is a next page.
    
    Returns:
    
    true if more data is available
  - stop
```
 void stop()
```
    Stops the handler.
