This class provides an API to various data sources used in BRIDGES.
BRIDGES currently supports a few external datasets for use with BRIDGES assignments: USGIS Earthquake Tweeet streaming data feed, IMDB (file), Book metadata collection, IGN Game Data, Shakespear book/poem meta data, etc.
Functions are provided that access a user specified number of data records; objects of the appropriate type are returned as a list.

old interface for the OSM data set.
This is hitting a simpler API that has only a few map in there: "uncc_campus", "charlotte", "washington_dc", "saint_paul", "new_york", "los_angeles", "san_francisco", "miami", "minneapolis", "dallas"
- Parameters
-
| location | which location to get the map from OSMData getOSMDataOld (string location) { std::transform(location.begin(), location.end(), location.begin(), ::tolower); std::string osm_json; bool from_cache = false; try { if (my_cache.inCache(location)) { osm_json = my_cache.getDoc(location); from_cache = true; } } catch (CacheException& ce) { something went bad trying to access the cache std::cout << "Exception while reading from cache. Ignoring cache and continue." << std::endl; } |
string url = string("http://osm-api.herokuapp.com/name/") + location;
if (!from_cache) { get the OSM data json osm_json = ServerComm::makeRequest(url, {"Accept: application/json"});
try { my_cache.putDoc(location, osm_json); } catch (CacheException& ce) { something went bad trying to access the cache std::cerr << "Exception while storing in cache. Weird but not critical." << std::endl; } }
return getOSMDataFromJSON(osm_json);
} Reconstruct a GraphAdjList from an existing GraphAdjList on the Bridges server
The reconstructed assignment sees vertices identified as integers in the order they are stored in the server. The data associated with a vertex is a string that comes from the label of that vertices. The data associated with an edge is the string that comes from the label of that edge. The edge weights are also reobtained from the bridges server.
- Parameters
-
| user | the name of the user who uploaded the assignment |
| assignment | the ID of the assignment to get |
| subassignment | the ID of the subassignment to get |
- Returns
- the ColorGrid stored in the bridges server
