Property Details

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

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

gdbVersion Property gdbVersion String

The geodatabase version to execute the function against. Defaults to SDE.DEFAULT when no version is provided.

moment Property moment Date

The date/timestamp (in UTC) to execute the function at a given time. This could be used to run the function in a moment in the past or in long transaction mode (undo/redo). Applicable to branch versioned datasets only.

The spatial reference that should be used to project the aggregated geometries returned by the trace (if applicable).

resultTypes Property resultTypes ResultTypeJSON[]

Parameter specifying the types of results to return after running a trace.

traceConfiguration Property traceConfiguration UNTraceConfiguration

Defines the properties of a trace.

traceLocations Property traceLocations TraceLocation[]

The list of starting points and barriers that will define where the trace starts and stops. This parameter can be optional (defaults to empty array) if minStartingPoints in NamedTraceConfiguration is set to none.

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.	TraceParameters
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.	TraceParameters

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.

Type Definitions

ResultTypeJSON Type Definition ResultTypeJSON Object

ResultTypeJSON specifies the type of results to return after running a trace.

Properties: type String

Specifies whether to return type "elements" or "aggregatedGeometry".

Possible Values:"elements"|"aggregatedGeometry"

includeGeometry Boolean

Specifies whether to return geometry values in resultTypes.

includePropagatedValues Boolean

Specifies whether to return propagated values in resultTypes.

networkAttributeNames String []

Specifies the network attribute names.

diagramTemplateName String

Specifies the name of a predefined Diagram Template.

resultTypeFields Object []

Specifies the types of output fields that can be generated from geoprocessing tools.

Example

// Creates a new instance of this class and initializes it with values inputted in json format. A resultTypes object is passed into the resultTypes property.
const traceParameters = TraceParameters.fromJSON({
   traceConfigurationGlobalId: "{DF22DA8D-6EC0-408B-A8B2-E468EC7DC9BF}",
   moment: 1554214441244,

   resultTypes: [
     {
       type: "elements",
