Property Overview

Property Details

declaredClassStringreadonly

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

dpiNumber

Resolution of the current map view in dots per inch.

Default Value: 96

geometryGeometry

The geometry used to select features during the Identify operation. The type of the geometry is specified by Geometry.type. The most common geometry used with Identify is a Point.

geometryPrecisionNumber

Specify the number of decimal places for the geometries returned by the task.

heightNumber

Height of the View in pixels.

Default Value: 400

layerIdsNumber[]

The layers on which to perform the identify operation. The layers are specified as a comma-separated list of layer IDs.

layerOptionString

Specifies which layers to use when using Identify.

Possible values	Description
top	Only the top-most visible layer is identified.
visible	All visible layers are identified.
all	All layers are identified, even if they are not visible. If your service has many layers, a request using this option will not perform well. A visible layer means you can see it in the map at the current extent. If a layer is turned off or not in range based on its scale dependency settings, it cannot be identified.

Default Value: top

mapExtentExtent

The Extent or bounding box of the current map view. The mapExtent property is assumed to be in the spatial reference of the map unless spatialReference has been specified.

The values for mapExtent, height, width, and dpi are used to determine the current map scale. Once the scale is known, the map service can exclude layers based on their scale dependency settings. The map service is not performing a spatial intersection based on the provided extent. These properties are also used to calculate the search distance on the map based on the tolerance in screen pixels.

maxAllowableOffsetNumber

The maximum allowable offset used for generalizing geometries returned by the identify operation. The offset is in the units of the spatialReference. If a spatialReference is not defined the spatial reference of the view is used.

returnGeometryBoolean

If true, the result set includes the geometry associated with each result.

Default Value: false

spatialReferenceSpatialReference

The spatial reference of the input and output geometries as well as of the mapExtent. If the spatial reference is not specified, the geometry and the extent are assumed to be in the spatial reference of the view, and the output geometries will also be in the spatial reference of the view.

toleranceNumber

The distance in screen pixels from the specified geometry within which the identify should be performed.

widthNumber

Width of the current map view in pixels.

Default Value: 400
