public enum StatisticMode
extends java.lang.Enum<StatisticMode>

Field statistics mode enumeration.

Provides common statistics for a single field. SuperMap provides six statistical functions, the maximum value, the minimum value, the average value of the statistical field, the sum, the standard deviation and the variance.

Enum Constant Summary

Enum Constants

Enum Constant and Description
AVERAGE The average value of the selected fields of the statistics.
MAX The maximum value of the selected fields of the statistics.
MIN The minimum value of the selected fields of the statistics.
STDDEVIATION The standard deviation of the selected fields of the statistics.
SUM The sum of the selected fields of the statistics.
VARIANCE The variance of the selected fields of the statistics.

Enum Constant Detail

AVERAGE

public static final StatisticMode AVERAGE

The average value of the selected fields of the statistics.

MAX

public static final StatisticMode MAX

The maximum value of the selected fields of the statistics.

MIN

public static final StatisticMode MIN

The minimum value of the selected fields of the statistics.

STDDEVIATION

public static final StatisticMode STDDEVIATION

The standard deviation of the selected fields of the statistics.

The formula of the standard deviation is ：

σ is the standard deviation, x is the field value of the selected field, n represents the number of elements contained in the field, and i is the integer from 1 to n, and M is the average value of the field.

SUM

public static final StatisticMode SUM

The sum of the selected fields of the statistics.

VARIANCE

public static final StatisticMode VARIANCE

The variance of the selected fields of the statistics.

The formula of the variance is ：

V is the variance, x is the field value of the selected field, n represents the number of elements contained in the field, and i is the integer from 1 to n, and M is the average value of the field.

Method Detail

values

public static StatisticMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (StatisticMode c : StatisticMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static StatisticMode valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
