    Detailed Description

    Points are the most straightforward geometries to define, and Point class constructors provide the same options as available on this builder. This builder class is provided mainly for consistency with other immutable geometries.

    The spatial reference must be set before using the builder and cannot be changed after the builder contains points.

    Member Function Documentation

    [explicit] PointBuilder::PointBuilder(const Esri::ArcGISRuntime::Point &point, QObject *parent = nullptr)

    Initializes a point builder from an existing point.

    • point - The point to be used as the starting point for further modifications.
    • parent - An optional parent.

    [explicit] PointBuilder::PointBuilder(const Esri::ArcGISRuntime::SpatialReference &spatialReference, QObject *parent = nullptr)

    Initializes a point builder from a SpatialReference.

    • spatialReference - The spatial reference to be used as the starting point for further modifications.
    • parent - An optional parent.

    [override virtual] PointBuilder::~PointBuilder()

    Destructor.

    [override virtual] Esri::ArcGISRuntime::GeometryBuilderType PointBuilder::geometryBuilderType() const

    Reimplements: GeometryBuilder::geometryBuilderType() const.

    Gets the GeometryBuilderType of this builder.

    double PointBuilder::m() const

    Gets the m-value of the point.

    See also setM().

    void PointBuilder::offsetBy(double offsetX, double offsetY)

    Offsets the point by the given offsets for the x and y dimension.

    • offsetX - The number of units to move the point on the x axis.
    • offsetY - The number of units to move the point on the y axis.

    void PointBuilder::setM(double m)

    Sets the M (measure) value of the point.

    • m - The m-value.

    See also m().

    void PointBuilder::setX(double x)

    Sets the x-coordinate of the point.

    • x - The x-coordinate.

    See also x().

    void PointBuilder::setXY(double x, double y)

    Sets the x and y coordinates of the point.

    • x - The x-coordinate.
    • y - The y-coordinate.

    void PointBuilder::setY(double y)

    Sets the y-coordinate of the point.

    • y - The y-coordinate.

    See also y().

    void PointBuilder::setZ(double z)

    Sets the z-coordinate of the point.

    • z - The z-coordinate.

    See also z().

    [override virtual] Esri::ArcGISRuntime::Geometry PointBuilder::toGeometry() const

    Reimplements: GeometryBuilder::toGeometry() const.

    Returns the point geometry this builder is constructing or modifying.

    Esri::ArcGISRuntime::Point PointBuilder::toPoint() const

    Returns the point geometry this builder is constructing or modifying.

    This is a convenience method to avoid having to cast the return value.

    double PointBuilder::x() const

    Gets the x-coordinate of the point.

    See also setX().

    double PointBuilder::y() const

    Gets the y-coordinate of the point.

    See also setY().

    double PointBuilder::z() const

    Gets the z-coordinate of the point.

    The minimum z-value is -6,356,752 meters, which is the approximate radius of the earth (the WGS 84 datum semi-minor axis). The maximum z-value is 55,000,000 meters.
