MGLComputedShapeSourceDataSource

+ 
@protocol MGLComputedShapeSourceDataSource <NSObject>
+ +
+
+

Data source for MGLComputedShapeSource. This protocol defines two optional methods for fetching +data, one based on tile coordinates, and one based on a bounding box. Classes that implement this +protocol must implement one, and only one of the methods. Methods on this protocol will not be +called on main thread, they will be called on the caller’s requestQueue.
