declaredClass

Inherited

Property declaredClass Stringreadonly

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

The image type (e.g. "jpg" or "tif") when this data type references an image.

Example

const parameterValue = await jobInfo.fetchResultData("Output_TIF_GDB");
console.log(parameterValue.dataType); // "raster-data-layer"

const rasterData = parameterValue.value;
console.log(rasterData.url);    // "https://machine.domain.com/webadaptor/rest/directories/arcgisoutput/GPServer/_ags_africa_150m.tif"
console.log(rasterData.format); // "tif"

The ID of the portal item containing the raster data file or service.

Example

const rasterData = new RasterData({
  itemId: "my-portal-item-id"
});

When the output data type is an image service, this property will return image-service.

For RasterData the type is always "image-service".

Example

const rasterData = parameterValue.value;
const { url, format, type } = rasterData;
if (url) {
  if (type === "image-service") {
    console.log(`The url to the image service is: ${url}`);
  else {
    console.log(`The url to the raster data file is: ${url}`);
    console.log(`The raster data file is a ${format} image`);
  }
}

The URL to the raster data file or image service.

addHandles

Inherited

Method addHandles(handleOrHandles, groupKey)

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

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.

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.

Returns

Type Description * | null | undefined Returns a new instance of this class.

Method hasHandles(groupKey){Boolean}

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

if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
}

removeHandles

Inherited

Method removeHandles(groupKey)

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.
