Class RasterCalcStatsHistogram

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

All Implemented Interfaces:

IRasterCalcStatsHistogram, IRasterCalcStatsHistogram2, IRasterCalcStatsHistogram3, com.esri.arcgis.interop.RemoteObjRef, Serializable

public class RasterCalcStatsHistogram
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, IRasterCalcStatsHistogram, IRasterCalcStatsHistogram2, IRasterCalcStatsHistogram3

A helper class for calculating raster statistics and histogram.

Remarks

RasterCalcStatsHistogram object is used to calculate the "unified" statistics and histogram for one or multiple raster bands.

RasterCalcStatsHistogram creates StatsHistogram object, which is used in RasterStretchColorRampRenderer .

Constructor Detail

RasterCalcStatsHistogram

public RasterCalcStatsHistogram()
                         throws IOException,
                                UnknownHostException

Constructs a RasterCalcStatsHistogram using ArcGIS Engine.

Throws:

IOException - if there are interop problems

UnknownHostException - if there are interop problems

RasterCalcStatsHistogram

public RasterCalcStatsHistogram(Object obj)
                         throws IOException

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

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

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
