Spatial Data Create/Update API

Backendless SDK includes special classes which facilitate saving of spatial data values in the database. The same classes are used to represent spatial data when it is retrieved from the database. For more information about data retrieval, see the Spatial Data Retrieval API section.

POINT Values

Consider the following table schema in Backendless database. Notice the pickupLocation and the dropoffLocation columns. Both are of type POINT:

sample-schema-geo

The following code demonstrates how to create a new object with POINT properties in the Order table:

Order class:

public class Order
{
    private Point pickupLocation;
    private Point dropoffLocation;
    private String orderName;
    private String objectId;

    public String getObjectId()
    {
        return objectId;
    }

    public void setObjectId( String objectId )
    {
        this.objectId = objectId;
    }

    public Point getPickupLocation()
    {
        return pickupLocation;
    }

    public void setPickupLocation( Point pickupLocation )
    {
        this.pickupLocation = pickupLocation;
    }

    public Point getDropoffLocation()
    {
        return dropoffLocation;
    }

    public void setDropoffLocation( Point dropoffLocation )
    {
        this.dropoffLocation = dropoffLocation;
    }

    public String getOrderName()
    {
        return orderName;
    }

    public void setOrderName( String orderName )
    {
        this.orderName = orderName;
    }
}
Code to create and save an order in the database:
Order myOrder = new Order();
myOrder.setOrderName( "Fun times" );
myOrder.setPickupLocation( new Point().setLatitude( 55.782309 ).setLongitude( 37.578639 ) );
myOrder.setDropoffLocation( new Point().setLatitude( 55.752917 ).setLongitude( 37.618900 ) );
Backendless.Data.of( Order.class ).save( myOrder, new AsyncCallback<Order>()
{
    @Override
    public void handleResponse( Order savedOrder )
    {
        String objectId = savedOrder.getObjectId();
    }

    @Override
    public void handleFault( BackendlessFault fault )
    {

    }
});

Order class:

class Order {
   var pickupLocation: Point? = null
   var dropoffLocation: Point? = null
   var orderName: String? = null
   var objectId: String? = null
}
Code to save a Order object in the database
val myOrder = Order()
myOrder.orderName = "Fun times"
myOrder.pickupLocation = Point().setLatitude(55.782309).setLongitude(37.578639)
myOrder.dropoffLocation = Point().setLatitude(55.752917).setLongitude(37.618900)
Backendless.Data.of(Order::class.java).save(myOrder, object : AsyncCallback<Order> {
   override fun handleResponse(savedOrder: Order) {
       val objectId = savedOrder.objectId
   }

   override fun handleFault(fault: BackendlessFault) {

   }
})

HashMap<String, Object> order = new HashMap<>(  );
order.put( "orderName", "Fun times" );
order.put( "pickupLocation", new Point().setLatitude( 55.782309 ).setLongitude( 37.578639 ) );
order.put( "dropoffLocation", new Point().setLatitude( 55.752917 ).setLongitude( 37.618900 ) );
Backendless.Data.of( "Order" ).save( order, new AsyncCallback<Map>()
{
    @Override
    public void handleResponse( Map savedOrder )
    {
        String objectId = (String) savedOrder.get( "objectId" );

    }

    @Override
    public void handleFault( BackendlessFault fault )
    {

    }
});
val order = HashMap<String, Any>()
order.put("orderName", "Fun times")
order.put("pickupLocation", Point().setLatitude(55.782309).setLongitude(37.578639))
order.put("dropoffLocation", Point().setLatitude(55.752917).setLongitude(37.618900))
Backendless.Data.of("Order").save(order, object : AsyncCallback<Map<Any?, Any?>> {
   override fun handleResponse(savedOrder: Map<Any?, Any?>) {
       val objectId = savedOrder["objectId"] as String?
   }

   override fun handleFault(fault: BackendlessFault) {

   }
})

Codeless Reference

The example below creates a new object containing two GeoJSON (Point) objects and saves it to the database called Order:

data_spatial_createupdate_1

where:

Argument                Description
table name Name of the data table where a new record must be saved.
object An object to save in the database. Object properties must match the names of the table columns. The object must not have the objectId property.
return result Optional parameter. When this box is checked, the operation returns the saved object with the objectId property.

When you run the code(or Codeless logic), you will see the following in the database:

sample-geo-create-map

LINESTRING Values

Creating objects with LINESTRING properties works similarly to the example shown above - your code needs to use corresponding class from the SDK. For example, the code below creates an object in the Travel table with a LINESTRING route:

Travel class:

public class Travel
{
    private String name;
    private LineString route;
    private String objectId;

    public String getName()
    {
        return name;
    }

    public void setName( String name )
    {
        this.name = name;
    }

    public LineString getRoute()
    {
        return route;
    }

    public void setRoute( LineString route )
    {
        this.route = route;
    }

    public String getObjectId()
    {
        return objectId;
    }

    public void setObjectId( String objectId )
    {
        this.objectId = objectId;
    }
}
Code to create and save an object in the database:

Notice the example above uses the LineString.fromWKT method to convert a string representation of a geometry into an instance of the LineString class. Alternatively, the code can use a constructor in the LineString class which takes an collection of Point objects. The example below and the one above produce exactly the same result using different approaches available in the SDK:

Travel class:

public class Travel
{
    private String name;
    private LineString route;
    private String objectId;

    public String getName()
    {
        return name;
    }

    public void setName( String name )
    {
        this.name = name;
    }

    public LineString getRoute()
    {
        return route;
    }

    public void setRoute( LineString route )
    {
        this.route = route;
    }

    public String getObjectId()
    {
        return objectId;
    }

    public void setObjectId( String objectId )
    {
        this.objectId = objectId;
    }
}
Code to create and save an object in the database:
Travel travelObject = new Travel();
travelObject.setName( "Route 66" );

Codeless Reference

The example below creates a new object containing one GeoJSON (LineString) object and saves it to the database called Travel:

data_spatial_createupdate_2

where:

Argument                Description
table name Name of the data table where a new record must be saved.
object An object to save in the database. Object properties must match the names of the table columns. The object must not have the objectId property.
return result Optional parameter. When this box is checked, the operation returns the saved object with the objectId property.

When you run the code(or Codeless Logic), you will see the following object in the database:

sample-linestring

POLYGON Values

Creating objects with properties of type POLYGON can be done by using the com.backendless.persistence.Polygon class. Consider the following example, it is a data table called Building with a schema which includes a column named shape of type POLYGON:

building-table-schema

The code below demonstrates how to create a new object with a POLYGON property in the database:

Building class:

import com.backendless.persistence.Polygon;

public class Building
{
    private String name;
    private Polygon shape;
    private String objectId;

    public String getName()
    {
        return name;
    }

    public void setName( String name )
    {
        this.name = name;
    }

    public Polygon getShape()
    {
        return shape;
    }

    public void setShape( Polygon shape )
    {
        this.shape = shape;
    }

    public String getObjectId()
    {
        return objectId;
    }

    public void setObjectId( String objectId )
    {
        this.objectId = objectId;
    }
}

Notice the example above uses the Polygon.fromWKT method to convert a string representation of a geometry into an instance of the Polygon class. Alternatively, the code can use a constructor in the Polygon class which accepts two collections - the boundary points and the holes. The example below and the one above produce exactly the same result using different approaches available in the SDK:

Building class:

import com.backendless.persistence.Polygon;

public class Building
{
    private String name;
    private Polygon shape;
    private String objectId;

    public String getName()
    {
        return name;
    }

    public void setName( String name )
    {
        this.name = name;
    }

    public Polygon getShape()
    {
        return shape;
    }

    public void setShape( Polygon shape )
    {
        this.shape = shape;
    }

    public String getObjectId()
    {
        return objectId;
    }

    public void setObjectId( String objectId )
    {
        this.objectId = objectId;
    }
}
Code to create and save an object in the database:

List<LineString> holes = new ArrayList<>();
holes.add( new LineString( hole ) );

Polygon pentagonBuildingShape = new Polygon( boundary, holes );

Codeless Reference

The example below creates a new object containing one GeoJSON (Polygon) object and saves it to the database called geolocation:

data_spatial_types_13

where:

Argument                Description
table name Name of the data table where a new record must be saved.
object An object to save in the database. Object properties must match the names of the table columns. The object must not have the objectId property.
return result Optional parameter. When this box is checked, the operation returns the saved object with the objectId property.

After running the code(or Codeless Logic), you will see the following object in the database:

data_spatial_types_14
