dojo.require("esri.tasks.FeatureSet")
Description

(Added at v1.0)

A collection of features returned from ArcGIS Server or used as input to tasks. Each feature in the FeatureSet may contain geometry, attributes, symbology, and an InfoTemplate. If the FeatureSet does not contain geometry, and only contains attributes, the FeatureSet can be treated as a table where each feature is a row object. Tasks that return FeatureSet include

QueryTask

,

Geoprocessor

, and

RouteTask

. In addition, Geoprocessor and RouteTask may require FeatureSet as input.

Constructor Details

Creates a new FeatureSet object. The constructor takes no parameters.

Creates a new FeatureSet object using a JSON object. (Added at v1.3)

Parameters: <Object> json Required A JSON object that contains feature set.

Property Details

The name of the layer's primary display field. The value of this property matches the name of one of the fields of the feature. Only applicable when the FeatureSet is returned from a task. It is ignored when the FeatureSet is used as input to a geoprocessing task.

Typically a layer has a limit on the number of features (i.e., records) returned by the query operation. See

FeatureLayer.maxRecordCount

property. If

maxRecordCount

is configured for a layer,

exceededTransferLimit

will be true if a query matches more than the

maxRecordCount

features and false otherwise.

Supported by ArcGIS Server version 10.1 and later. (Added at v2.8)

Known values: true | false

The array of graphics returned.

Sample: 
var features = [];
features.push(graphic);
var featureSet = new esri.tasks.FeatureSet();
featureSet.features = features;

Set of name-value pairs for the attribute's field and alias names.

The array of fields. (Added at v3.18)

The geometry type of the FeatureSet.

When a FeatureSet is used as input to

Geoprocessor

, the spatial reference is set to the map's spatial reference by default. This value can be changed. When a FeatureSet is returned from a task, the value is the result as returned from the server. See

Projected Coordinate Systems

and

Geographic Coordinate Systems

for the list of supported spatial references.
