[override virtual noexcept] Point::~Point()
Destructor
[static] Esri::ArcGISRuntime::Point Point::createWithM(double x, double y, double m)
Returns a point with an x,y coordinates and m-value.
[static] Esri::ArcGISRuntime::Point Point::createWithM(double x, double y, double m, const Esri::ArcGISRuntime::SpatialReference &spatialReference)
Returns a point with an x, y, m and spatial reference.
M-values are used in linear referencing scenarios and may represent things like mile markers along a highway. Like z-values, every geometry can optionally store m-values with the point coordinates that comprise it. The default m-value is NaN. If an m-value is specified when a geometry is created, the new geometry has m-values (Geometry::hasM is true). Note that when you get m-values back from a geometry, the default value of NaN is returned for vertices that do not have m-values. A geometry with m-values is sometimes known as an m-aware geometry.

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.
Returns a Point with the specified coordinates and m-value in the given spatial reference. 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.
M-values are used in linear referencing scenarios and may represent things like mile markers along a highway. Like z-values, every geometry can optionally store m-values with the point coordinates that comprise it. The default m-value is NaN. If an m-value is specified when a geometry is created, the new geometry has m-values (Geometry::hasM is be true). Note that when you get m-values back from a geometry, the default value of NaN is returned for vertices that do not have m-values. A geometry with m-values is sometimes known as an m-aware geometry.
Geometries can have z-values, indicating values along the z-axis, which is perpendicular to both the x-axis and y-axis. Z-values indicate height above or depth below a surface, or an absolute elevation. For example, z-values are used to draw the locations of geometries in a SceneView. Note that geometries are not considered true 3D shapes and are draped onto surfaces in the view, or in some cases, drawn in a single plane by using z-values. Z-values are stored on Point and Envelope. Because Multipoint, Polyline, and Polygon are created from a collection of Point, all types of geometry can have z-values.
Whether or not a geometry has z-values is determined when the geometry is created; if you use a method that has a z-value parameter, the new geometry has z-values (Geometry::hasZ is true). If you create geometries using constructors that take z-value parameters, or if you pass into the constructor points or segments that have z-values, the new geometry has z-values. A Geometry with z-values is sometimes known as a z-aware geometry.
It may be that not all vertices in your geometry have a z-value defined. NaN is a valid z-value used to indicate an unknown z-value. However, the default z-value is 0. When you get z-values from a geometry that does not have z-values, the default is 0. Check the Geometry::hasZ to determine whether a z-value of 0 means that there are no z-values in the geometry or that the z-value in the geometry's coordinates really is 0.
