@Internal
public interface IOEventHandler

IOEventHandler interface is used by I/O reactors to handle I/O events for individual I/O sessions. All methods of this interface are executed on a single dispatch thread of the I/O reactor. Therefore, it is important that event processing does not not block the I/O dispatch thread for too long, thus making the I/O reactor unable to react to other events.
