Class RasterCalcUniqueValues

java.lang.Object
  com.esri.arcgis.datasourcesraster.RasterCalcUniqueValues

All Implemented Interfaces:

IRasterCalcUniqueValues, IRasterCalcUniqueValues2, com.esri.arcgis.interop.RemoteObjRef, Serializable

public class RasterCalcUniqueValues
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, IRasterCalcUniqueValues, IRasterCalcUniqueValues2

A helper class for calculating raster unique values.

Remarks

RasterCalcUniqueValues is used to obtain the unique values from one or a collection of raster datasets and use these "unified" unique values to render many rasters or some raster datasets in a raster catalog.

RasterCalcUniqueValues creates UniqueValues object, which is used in RasterUniqueValueRenderer.

Constructor Detail

RasterCalcUniqueValues

public RasterCalcUniqueValues()
                       throws IOException,
                              UnknownHostException

Constructs a RasterCalcUniqueValues using ArcGIS Engine.

Throws:

IOException - if there are interop problems

UnknownHostException - if there are interop problems

RasterCalcUniqueValues

public RasterCalcUniqueValues(Object obj)
                       throws IOException

Deprecated. As of ArcGIS 9.2, replaced by normal Java casts.
RasterCalcUniqueValues theRasterCalcUniqueValues = (RasterCalcUniqueValues) obj;

Construct a RasterCalcUniqueValues using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to RasterCalcUniqueValues.

Parameters:

obj - an object returned from ArcGIS Engine or Server

Throws:

IOException - if there are interop problems

Method Detail

getClsid

public static String getClsid()

getClsid.

equals

public boolean equals(Object o)

Compare this object with another

Overrides:

equals in class Object

hashCode

public int hashCode()

the hashcode for this object

Overrides:

hashCode in class Object
