Number	The `bevelRatio` is multiplied by the offset distance and the result determines how far a mitered offset intersection can be located before it is beveled.	OffsetParameters

Geometry []	The array of geometries to be offset.	OffsetParameters
Number	Specifies the planar distance for constructing an offset based on the input geometries.	OffsetParameters

String	The offset distance unit.	OffsetParameters

Property Details

bevelRatio Property bevelRatio Number

The bevelRatio is multiplied by the offset distance and the result determines how far a mitered offset intersection can be located before it is beveled. When mitered is specified, the value set for bevelRatio is ignored and 10 is used internally. If beveled is specified, 1.1 will be used if no value is set for bevelRatio. The bevelRatio is ignored when rounded is specified.

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.7 Accessor since 4.0, declaredClass added at 4.7.

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

geometries Property geometries Geometry[]

The array of geometries to be offset.

offsetDistance Property offsetDistance Number

Specifies the planar distance for constructing an offset based on the input geometries. If the offsetDistance parameter is positive, the constructed offset will be on the right side of the curve. Left side offsets are constructed with negative values.

offsetHow Property offsetHow String

Options that determine how the ends intersect. Set to one of the following options:

Possible Value	Description
bevelled	Squares off the corner after a given ratio distance.
mitered	Attempts to allow extended offsets to naturally intersect. If the intersection occurs too far from a corner, the corner will be beveled off at a fixed distance.
rounded	Rounds the corner between extended offsets.

Possible Values:"bevelled" |"mitered" |"rounded"

offsetUnit Property offsetUnit String

The offset distance unit. For a list of valid units see esriSRUnitType constants or esriSRUnit2Type constants.

Return Type	Summary	Class
	Adds one or more handles which are to be tied to the lifecycle of the object.	Accessor
*	Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product.	OffsetParameters
Boolean	Returns true if a named group of handles exist.	Accessor
	Removes a group of handles owned by the object.	Accessor
Object	Converts an instance of this class to its ArcGIS portal JSON representation.	OffsetParameters

Method Details

addHandles Inherited Method addHandles(handleOrHandles, groupKey) Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor 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();

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.

fromJSON Method fromJSON(json){*}static

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.

Parameter

json Object

A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.

Returns

Type	Description
*	Returns a new instance of this class.

hasHandles Inherited Method hasHandles(groupKey){Boolean} Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, hasHandles added at 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 Inherited Method removeHandles(groupKey) Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, removeHandles added at 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 Method toJSON(){Object}

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

Returns

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