Property Details
-
The name of the class. The declared class name is formatted as
esri.folder.className
.
-
Autocasts from Object
-
Input geometry that defines the locations to be sampled. The geometry can be a point, multipoint, polyline, extent or a polygon.
The locations property can be used to set an array of points for convenience if the geometry is a
multipoint
. If you set thelocations
property, the array of points will be converted to amultipoint
geometry at runtime.
-
interpolation String
-
Defines how to interpolate pixel values.
Possible Values:"nearest"|"bilinear"|"cubic"|"majority"
- Default Value:nearest
-
When sampling multiple locations, you can use an array of points instead of providing a multipoint for the geometry property. The array of points will be converted to a
multipoint
and used as the geometry at runtime. The first point's spatial reference is used ingetSamples
operation.
-
mosaicRule MosaicRuleautocastAutocasts from Object
-
Specifies the mosaic rule defining the image sort order and selection. When a mosaic rule is not specified, the current settings on the ImageryLayer will be used.
-
The list of fields associated with the rasters to be included in the response.
- Default Value:null
-
Autocasts from Object
-
Specifies the pixel size (or the resolution) that will be used for the sampling. If pixel size is not specified,
pixelSize
will default to the base resolution of the image service. The raster at the specified pixel size in the mosaic dataset will be used for this operation.
-
returnFirstValueOnly Boolean
-
When
true
, returns the first valid pixel value that meets specified conditions at each sampling point location. Whenfalse
, all pixel values are returned.- Default Value:true
-
sampleCount Number
-
Specifies the approximate number of locations to sample from the provided geometry when the input geometry is polyline, polygon or extent. Either
sampleDistance
orsampleCount
is needed to perform densification on the input polyline to sample points. The unit of the geometry's spatial reference will be used for the densification.
-
sampleDistance Number
-
Specifies the distance interval to sample points from the provided geometry when input geometry is polyline. Either
sampleDistance
orsampleCount
is needed to perform densification on the input polyline to sample points. The unit of the geometry's spatial reference will be used for the densification.
-
sliceId Number
-
Specifies the slice id of a multidimensional raster. This parameter is supported at ArcGIS Server 10.9 and later.
-
timeExtent TimeExtentautocastAutocasts from Object
-
The time extent for which to perform sampling. This parameter is supported at ArcGIS Server 10.9 and later.

Method Details
-
addHandles(handleOrHandles, groupKey)inheritedSince: ArcGIS Maps SDK for JavaScript 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();
ParametershandleOrHandles WatchHandle|WatchHandle[]Handles marked for removal once the object is destroyed.
groupKey *optionalKey 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(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.Parameterjson ObjectA 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.
ReturnsType Description * Returns a new instance of this class.
-
Since: ArcGIS Maps SDK for JavaScript 4.25
-
Returns true if a named group of handles exist.
ParametergroupKey *optionalA group key.
ReturnsType 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(groupKey)inheritedSince: ArcGIS Maps SDK for JavaScript 4.25
-
Removes a group of handles owned by the object.
ParametergroupKey *optionalA group key or an array or collection of group keys to remove.
Exampleobj.removeHandles(); // removes handles from default group obj.removeHandles("handle-group"); obj.removeHandles("other-handle-group");
-
toJSON(){Object}
-
Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.
ReturnsType Description Object The ArcGIS portal JSON representation of an instance of this class.
