Property Details

bufferSpatialReference SpatialReference

The spatial reference in which the geometries are buffered.

If bufferSpatialReference is not specified, the geometries are buffered in the spatial reference specified by outSpatialReference. If outSpatialReference is also not specified, they are buffered in the spatial reference of the features.

declaredClass Stringreadonly inherited

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

distances Number []

The distances the input features are buffered. The distance units are specified by unit.

geodesic Boolean

If the input geometries are in a geographic coordinate system, set geodesic to true to generate a buffer polygon using a geodesic distance. The bufferSpatialReference property is ignored when geodesic is set to true. Requires ArcGIS Server 10.1 or greater geometry service. For more information, see the ArcGIS REST API documentation on the GeometryService buffer operation and the geodesic property.

geometries Geometry []

The input geometries to buffer.

outSpatialReference SpatialReference

The spatial reference for the returned geometries.

If outSpatialReference is not specified, the output geometries are in the spatial reference specified by bufferSpatialReference. If bufferSpatialReference also is not specified, they are in the spatial reference of the features.

unionResults Boolean

If true, all geometries buffered at a given distance are unioned into a single (possibly multipart) polygon, and the unioned geometry is placed in the output array.

unit String

The units for calculating each buffer distance. If unit is not specified, the units are derived from bufferSpatialReference. If bufferSpatialReference is not specified, the units are derived from the features.

For a list of valid units, see esriSRUnitType Constants and esriSRUnit2Type Constants.
