Interface IStatisticsResults

All Superinterfaces:

Serializable

All Known Implementing Classes:

BaseStatistics, BasicTableHistogram, DataHistogram, IStatisticsResultsProxy, ServerStatisticsResults, TableHistogram, TinHistogram

public interface IStatisticsResults
extends Serializable

Provides access to members used for reporting statistics.

Description

IStatisticsResults is implemented by the BaseStatistics object and also by the histogram
objects (see esriCartoUI). Its use is straightforward, the only point to note is for the StandardDeviation property—if your data is a sample of the real data, you should indicate so with IGenerateStatistics::Sample before calling StandardDeviation.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Method Summary

int	getCount() The count of the values.
double	getMaximum() The maximum value.
double	getMean() The arithmetic mean.
double	getMinimum() The minimum value.
double	getStandardDeviation() The standard deviation, based on sample flag.
double	getSum() The sum of the values.

Method Detail

getCount

int getCount()
             throws IOException,
                    AutomationException

The count of the values.

Description

Returns the Count of data values in the BaseStatistics used to derive the statistics. Use this property when IGenerateStatistics.SimpleStats is set to true.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Returns:

The count

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getMinimum

double getMinimum()
                  throws IOException,
                         AutomationException

The minimum value.

Description

Returns the Minimum data values in the BaseStatistics. Use this property when IGenerateStatistics.SimpleStats is set to true.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Returns:

The min

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getMaximum

double getMaximum()
                  throws IOException,
                         AutomationException

The maximum value.

Description

Returns the Maximum data values in the BaseStatistics. Use this property when IGenerateStatistics.SimpleStats is set to true.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Returns:

The max

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getSum

double getSum()
              throws IOException,
                     AutomationException

The sum of the values.

Description

Returns the Sum of all the data values in the BaseStatistics. Use this property when IGenerateStatistics.SimpleStats is set to true.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Returns:

The sum

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getMean

double getMean()
               throws IOException,
                      AutomationException

The arithmetic mean.

Description

Returns the arithmetic Mean of all the data values in the BaseStatistics. Use this property when IGenerateStatistics.SimpleStats is set to true.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Returns:

The mean

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getStandardDeviation

double getStandardDeviation()
                            throws IOException,
                                   AutomationException

The standard deviation, based on sample flag.

Description

Returns the StandardDeviation of all the data values in the BaseStatistics.

If your data is a sample of the real data, you should indicate so with IGenerateStatistics::Sample before calling StandardDeviation.

Remarks

By default it returns the Sample Standard Deviation.

Product Availability

Supported Platforms

Windows, Solaris, Linux

Returns:

The stdDev

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
