public interface SliderSlide
The SliderSlide object provides slide metadata and allows the download of related images.
These objects are obtained by the client application either through the
SliderListener.onSlidesAdded(List)
listener method orSlider.getSlides()
method.There is a 1-1 correspondence between SliderSlide instances and actual slides, so they can be compared by reference.

cancelThumbnailFetching
void cancelThumbnailFetching()
Cancels pending
fetchThumbnail(FetchImageCompletionHandler)
requests.Fetch requests may be serialized internally so that only a couple (possibly one) simultaneous server request is sent at any given moment. This can result in high latencies for any new requests if client previously issued fetch requests for many slides during a small period of time. This method allows to cancel some earlier requests before they finish if client is not interested in the result anymore and therefore reduce time required to finish newer requests.
