Detailed Description
Point geometries are immutable and cannot be changed directly once created. The PointBuilder has a number of constructors to allow you to create a new point, or you can edit an existing point using setXY(double, double) or offsetBy(double, double). Use GeometryBuilder::toGeometry to return the new Point from the builder.
Member Function Documentation
[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.
