ExternalInfo class Landmarks
Wikipedia information for a Landmark.
An ExternalInfo instance exposes article metadata (title, summary, language and URL) and image-related helpers (count, titles, URLs and asynchronous loaders). Instances are created by the platform and returned via ExternalInfoService.requestWikiInfo; do not construct this class directly.
