Workflow | API Reference | ArcGIS Maps SDK for JavaScript 4.31

The read-only Workflow class helps manage different stages of an editing workflow. A workflow can be thought of as one of two types: CreateFeaturesWorkflow and UpdateWorkflow. If adding an individual or multiple features, the CreateFeaturesWorkflow is used. Whereas if editing an existing feature, the UpdateWorkflow is used. Updating workflows include both editing geometry and attribute data and deleting features.

An instance of either a CreateFeaturesWorkflow or UpdateWorkflow is accessed via the activeWorkflow property in either the Editor or EditorViewModel classes.

These workflows are only enabled if the feature service allows these operations. For example, if a feature service is only enabled to allow updates, it is not possible to override this using the API.

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.

cancel Method cancel(options){Promise<void>}
