public class UniqueValues
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, IUniqueValues, IUniqueValues2, IUniqueStringValues, IUniqueMutliStringValues, IUniqueDoubleValues, IPersist, IPersistStream, IXMLSerialize, Externalizable

A raster unique value class.

Description

The UniqueValues object creates and maintains a list of unique values and the associated counts. UniqueValues is a helper object that provides pixel value information, the unique values and the associated counts, of a raster for RasterUniqueValueRenderer and RasterClassifyColorRampRenderer objects. The UniqueValues can be obtained either by co-creating from this object or by calculating using RasterCalcUniqueValues object.
