Interface SubscriptionEventListener

All Known Subinterfaces:

ChannelEventListener, PresenceChannelEventListener, PrivateChannelEventListener

public interface SubscriptionEventListener

Client applications should implement this interface if they want to be notified when events are received on a public or private channel.

To bind your implementation of this interface to a channel, either:

• Call Pusher.subscribe(String) to subscribe and receive an instance of Channel.
• Call Channel.bind(String, SubscriptionEventListener) to bind your listener to a specified event.

Or, call Pusher.subscribe(String, ChannelEventListener, String...) to subscribe to a channel and bind your listener to one or more events at the same time.
