Property Overview
Name | Type | Summary | Class |
---|---|---|---|
The name of the class. | Accessor | ||
The input geometries to project. | ProjectParameters | ||
The spatial reference to which you are projecting the geometries. | ProjectParameters | ||
The well-known id {wkid:number} or well-known text {wkt:string} of the datum transformation to be applied to the projected geometries. | ProjectParameters | ||
Indicates whether to transform forward or not. | ProjectParameters |
Property Details
-
outSpatialReference
outSpatialReference SpatialReference
Since: ArcGIS Maps SDK for JavaScript 4.4ProjectParameters since 4.0, outSpatialReference added at 4.4. -
The spatial reference to which you are projecting the geometries.
-
transformation
transformation Object
-
The well-known id {wkid:number} or well-known text {wkt:string} of the datum transformation to be applied to the projected geometries. See Datum transformations for a list of valid datum transformations that may be used here.
If a transformation is specified, a value must also be specified in the transformForward property.
- Properties
-
wkid Number
The well-known ID of the datum transformation to apply to the projection. List of valid IDs for Datum transformations.
wkt StringThe well-known text that defines a spatial reference. Many browsers have a limit to the length of a GET request of approximately 2048 characters. When using well-known text to specify the spatial reference you can easily exceed this limit. In these cases, you will need to setup and use a proxy page.
-
transformForward
transformForward Boolean
-
Indicates whether to transform forward or not. The forward or reverse direction of transformation is implied in the name of the transformation.

Method Details
-
Inherited from Accessor
Since: ArcGIS Maps SDK for JavaScript 4.25Accessor since 4.0, addHandles added at 4.25. -
Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.
// Manually manage handles const handle = reactiveUtils.when( () => !view.updating, () => { wkidSelect.disabled = false; }, { once: true } ); this.addHandles(handle); // Destroy the object this.destroy();
ParametershandleOrHandles WatchHandle|WatchHandle[]Handles marked for removal once the object is destroyed.
groupKey *optionalKey identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.
-
hasHandles
InheritedMethodhasHandles(groupKey){Boolean}
Inherited from AccessorSince: ArcGIS Maps SDK for JavaScript 4.25Accessor since 4.0, hasHandles added at 4.25. -
Returns true if a named group of handles exist.
ParametergroupKey *optionalA group key.
ReturnsType Description Boolean Returns true
if a named group of handles exist.Example// Remove a named group of handles if they exist. if (obj.hasHandles("watch-view-updates")) { obj.removeHandles("watch-view-updates"); }
-
Inherited from Accessor
Since: ArcGIS Maps SDK for JavaScript 4.25Accessor since 4.0, removeHandles added at 4.25. -
Removes a group of handles owned by the object.
ParametergroupKey *optionalA group key or an array or collection of group keys to remove.
Exampleobj.removeHandles(); // removes handles from default group obj.removeHandles("handle-group"); obj.removeHandles("other-handle-group");
-
toJSON
toJSON(){Object}
-
Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() topic in the Guide for more information.
ReturnsType Description Object The ArcGIS portal JSON representation of an instance of this class.
