public long indexOf(@Nullable
                    GLMapVectorObject object)

Returns index of object

Parameters:

object - object to search

Returns:

index of object or -1

findNearPoint

@Nullable
public GLMapVectorObject findNearPoint(long startIndex,
                                       long endIndex,
                                       @NonNull
                                       GLMapViewRenderer mapView,
