QueryChannelsController

```
public interface QueryChannelsController

                    
```
The QueryChannelsController is a small helper to show a list of channels
- .channels a livedata object with the list of channels. this list
- .loading if we're currently loading
- .loadingMore if we're currently loading more channels

Modifier and Type	Class	Description
`public class`	`QueryChannelsController.ChannelsState`

Method Summary

Modifier and Type	Method	Description
`abstract FilterObject`	`getFilter()`	The filter used for this query
`abstract QuerySort<Channel>`	`getSort()`	The sort used for this query
`abstract ChatEventHandler`	`getChatEventHandler()`	Instance of ChatEventHandler that handles logic of event handling for this QueryChannelsController.
`abstract Unit`	`setChatEventHandler(ChatEventHandler chatEventHandler)`	Instance of ChatEventHandler that handles logic of event handling for this QueryChannelsController.
`abstract Boolean`	`getRecoveryNeeded()`	If the API call failed and we need to rerun this query
`abstract LiveData<Boolean>`	`getEndOfChannels()`	If we've reached the end of the channels
`abstract LiveData<List<Channel>>`	`getChannels()`	The list of channels Typically we recommend using channelsState instead, it's a bit more complex but ensures that you're handling all edge cases
`abstract LiveData<QueryChannelsController.ChannelsState>`	`getChannelsState()`	Similar to the channels field, but returns the a ChannelsState object This sealed class makes it easier to verify that you've implemented all possible error/no result states
`abstract LiveData<Boolean>`	`getLoading()`	If we are currently loading channels
`abstract LiveData<Boolean>`	`getLoadingMore()`	If we are currently loading more channels
