    [override virtual] MultipartBuilder::~MultipartBuilder()

    Destructor.

    int MultipartBuilder::addPoint(const Esri::ArcGISRuntime::Point &point)

    Adds a new point to the end of the part.

    A new line segment will be added to connect the new point to the previous. The points in the part are the start and end points of segments. A new line segment is added to connect the new point to the previous point. If this is the first point in an empty segment, a single closed segment is added using the same start and end point. Adding a second point will update this line segment to gain a distinct end point. Adding a third or more points will add new line segments.

    int MultipartBuilder::addPoint(double x, double y)

    Returns adds a new point to the end of the last part of the multipart.

    • x - The x coordinate of the point to add.
    • y - The y coordinate of the point to add.

    If there are no parts then an initial part is created and the point added to that. The point will become the end point of a line segment in the part.

    int MultipartBuilder::addPoint(double x, double y, double z)

    Returns adds a new point to the end of the last part of the multipart.

    • y - The y coordinate of the point to add.
    • z - The z coordinate of the point to add.

    void MultipartBuilder::addPoints(const QList<Esri::ArcGISRuntime::Point> &points)

    Adds a list of points to the Multipart.

    Esri::ArcGISRuntime::PartCollection *MultipartBuilder::parts() const

    Gets the parts of this MultipartBuilder as a PartCollection.

    Returns a PartCollection.

    void MultipartBuilder::setParts(Esri::ArcGISRuntime::PartCollection *parts)

    Sets the parts of this MultipartBuilder to parts.
