ProjectParameters

Property Overview

Property Details

declaredClass Stringreadonly inherited

Since: ArcGIS Maps SDK for JavaScript 4.7

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

geometries Geometry[]

The input geometries to project.

outSpatialReference SpatialReference

Since: ArcGIS Maps SDK for JavaScript 4.4

The spatial reference to which you are projecting the geometries.

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 optional The well-known ID of the datum transformation to apply to the projection. List of valid IDs for Datum transformations.

wkt String optional The 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 Boolean

Indicates whether to transform forward or not. The forward or reverse direction of transformation is implied in the name of the transformation.

Method Overview

Method Details

addHandles(handleOrHandles, groupKey)inherited

Since: ArcGIS Maps SDK for JavaScript 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();

Parameters

handleOrHandles WatchHandle|WatchHandle[] Handles marked for removal once the object is destroyed.

groupKey * optional Key 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(groupKey){Boolean}inherited

Since: ArcGIS Maps SDK for JavaScript 4.25

Returns true if a named group of handles exist.

Parameter

groupKey * optional A group key.

Returns

Type	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");
}

removeHandles(groupKey)inherited

Since: ArcGIS Maps SDK for JavaScript 4.25

Removes a group of handles owned by the object.

Parameter

groupKey * optional A group key or an array or collection of group keys to remove.

Example

obj.removeHandles(); // removes handles from default group

obj.removeHandles("handle-group");
obj.removeHandles("other-handle-group");

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.

Returns

Type	Description
Object	The ArcGIS portal JSON representation of an instance of this class.
