Find Documents By Location with paging

Question

I think would be a very useful api call to have. i current have an app with a list of geo referenced images and sort them by location with many images at a single location, I don't want them all at once as it makes the loading of the app really slow as they are all downloaded at once, i would like to show say five and then make a call for the next 5 etc

Hi Aaron,

 

 

 

Please find below code snippet for the same and let me know if you required any other help from our side:

 

String dbName = "<Your_DataBase_Name>";

String collectionName = "<Your_Collection_Name>"; 

GeoTag gp = new GeoTag();

gp.SetLat(-73.99171);

gp.SetLng(40.738868);

GeoQuery query = QueryBuilder.BuildGeoQuery(gp, GeoOperator.NEAR, new BigDecimal(100));

App42Log.SetDebug(true); //Print output in your editor console

App42API.Initialize("API_KEY","SECRET_KEY");

StorageService storageService = App42API.BuildStorageService(); 

storageService.SetPageOffset(0);  // Based on page index, change the value offset value 

storageService.SetPageMaxRecords(10); 

storageService.SetGeoTag(gp);

storageService.FindDocumentsByLocation(dbName, collectionName, query, new UnityCallBack()); 

public class UnityCallBack : App42CallBack

{

public void OnSuccess(object response)

{

Storage storage = (Storage) response;

IList<Storage.JSONDocument> jsonDocList = storage.GetJsonDocList(); 

for(int i=0;i <jsonDocList.Count;i++)

{   

App42Log.Console("objectId is " + jsonDocList[i].GetDocId());

App42Log.Console("jsonDoc is " + jsonDocList[i].GetJsonDoc());

}  

}

 

public void OnException(Exception e)

{

App42Log.Console("Exception : " + e);

}

}
