GraphApplyEdits | API Reference | ArcGIS Maps SDK for JavaScript 4.30

This class defines entities and relationships to add, delete, and update in a knowledge graph service's graph resource. Use entityUpdates or relationshipUpdates to change property values.

Note

The user must have sufficient privileges to edit content, and editing must be enabled for the knowledge graph service for this operation to be successful.

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.

A list of entities to add to the knowledge graph.

Example

//add a new `Supplier` entity
const newEntity = new Entity({
  typeName: "Supplier",
  properties: {
    Name: "Supplier 5",
    EmployeeCount: 681
  }

A list of objects containing an entity type and the ids of the entities of that type to delete. Each object must have thetypeName and ids properties.

Example

entityDeletes: [{
   typeName: "Supplier",
   ids: ["{AMGIE541G-41F1-49A4-8412-CACCC9906E88}", "{HNWIGHE15-WH52-2GE6-1A5W-A1F8W4FS3A1S5}"]

options Property options Object

Additional options to set an input quantization for any geometries being added to the graph and to automatically delete all relationships associated with a deleted entity.

Properties: inputQuantizationParameters InputQuantizationParameters

Custom quantization parameters for input geometry that compresses geometry for transfer to the server. Overrides the default lossless WGS84 quantization.

cascadeDelete Boolean

If true, deleting an entity will automatically delete all relationships connected to that entity. If false, then both the entity and all it's connected relationships must be provided or the executeApplyEdits() operation will fail.
Default Value:false

Return Type	Summary	Class
	Adds one or more handles which are to be tied to the lifecycle of the object.	Accessor
Boolean	Returns true if a named group of handles exist.	Accessor
	Removes a group of handles owned by the object.	Accessor

Method Details

addHandles Inherited Method addHandles(handleOrHandles, groupKey) Inherited from Accessor

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 Inherited Method hasHandles(groupKey){Boolean} Inherited from Accessor

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

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");

Type Definitions

GraphNamedObjectDeletes Type Definition GraphNamedObjectDeletes Object

GraphNamedObjectDeletes represents the list of GraphNamedObjects (entities or relationships) of a specific type that will be deleted from a knowledge graph.

Properties: typeName String

The name of the EntityType that the entities belongs to.

ids String []

A list of the ids of the specified type to delete.

Example

//typical use case
GraphApplyEdits.entityDeletes = [{
   typeName: "Supplier",
   ids: ["{AMGIE541G-41F1-49A4-8412-CACCC9906E88}", "{HNWIGHE15-WH52-2GE6-1A5W-A1F8W4FS3A1S5}"]
