      • add

        public void add​(@NonNull
                PointData point)

        Adds a new point to the data source. Altitude of the point coordinates is ignored.

        Parameters:
        point -

        Point to be added.

      • add

        public void add​(@NonNull
                java.util.List<PointData> points)

        Adds new points to the data source. Altitude of the points coordinates is ignored.

        Parameters:
        points -

        Point positions.

      • removeAll

        public void removeAll()

        Removes all points from the data source.

      • forEach

        public void forEach​(@NonNull
                    PointDataSource.PointDataProcessor processor)

        Iterates through all the points from the data source and passes them to the given processor, one by one. The processor can update the point data.

        The iteration stops after all points have been processed or the processor returns false from the process call.

        Parameters:
        processor -

        Point data processor.

      • removeIf

        public void removeIf​(@NonNull
                     PointDataSource.PointDataProcessor processor)

        Iterates through all the points from the data source and passes them to the given inspector, one by one. All points for which the inspector returns true get removed from the data source. The inspector cannot update the point data.

        Parameters:
        processor -

        Point data processor.

      • destroy

        public void destroy()

        Frees all internally used resources. After calling this method, the object is not usable anymore.
