Point

The cache is used to store values computed from geometries that need to be cleared or recomputed upon mutation. An example is the extent of a polygon.

The name of the class. The declared class name is formatted as esri.folder.className.

The extent of the geometry. For a point, the extent is null.

Indicates if the geometry has m-values (measure). M-values allow attribute values to be stored with the geometry.

• true: The geometry is m aware. M-values are part of the geometry coordinates.
• false: The geometry is not m aware. M-values are not part of the coordinates.

See also

• Point.m for more information on how m-values are represented in geometries.

• returnM for details regarding fetching m-values with features from a layer

• Linear referencing

Indicates if the geometry has z-values (elevation).

• true: The geometry is z aware. Z-values are part of the geometry coordinates.
• false: The geometry is not z aware. Z-values are not part of the coordinates.

• Point.z for more information on how z-values are represented in geometries

• returnZ for details regarding fetching z-values with features from a layer

The latitude of the point. If the spatial reference is Web Mercator, the latitude will be given in WGS84. In any geographic spatial reference, the latitude will equal the y coordinate. In all other cases the latitude will be null.

The longitude of the point. If the spatial reference is Web Mercator, the longitude will be given in WGS84. In any geographic spatial reference, the longitude will equal the x coordinate. In all other cases the longitude will be null.

The m-value (measure) of the point.

• Linear referencing

The spatial reference of the geometry.

The string value representing the type of geometry.

The x-coordinate (easting) of the point in map units.

The y-coordinate (northing) of the point in map units.

The z-coordinate (or elevation) of the geometry. The units of the z-values are expressed by the vertical unit of the service's vertical coordinate system (VCS) if one is defined. In the absence of a VCS, the vertical units default to the linear units of the service's horizontal coordinate system. If the service's coordinate system is a geographic coordinate system, the z-values are expressed in meters.

For display purposes, z-values are automatically scaled to match the linear unit of the view's spatial reference. For example, if a service is in a State Plane projection (with linear units in us feet) but the view's spatial reference is Web Mercator, any displayed z-values (such as in labels) will be scaled and shown in meters.

Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Creates a deep clone of Point object.

Copies all values from another Point instance.

Computes the Euclidean distance between this Point and a given Point. Points must have the same spatial reference.

Determines if the input point is equal to the point calling the function.

Modifies the point geometry in-place by shifting the X-coordinate to within +/- 180 span in map units. You should clone() the point object before calling this method where appropriate.

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.
