Enum Constant Detail

TRANSFORM

public static final CalculationOperation TRANSFORM

Transform the grade entries between the GradeSystems defined in the input and the target columns.

MEAN

public static final CalculationOperation MEAN

Calculate the mean of the linked column entries.

MEDIAN

public static final CalculationOperation MEDIAN

Calculate the median of the linked column entries.

MODE

public static final CalculationOperation MODE

Calculate the mode of the linked column entries.

PERCENTILE

public static final CalculationOperation PERCENTILE

Calculate the percentile of the linked column. If more than one column is selected, the mean of the row entries is used.

RMS

public static final CalculationOperation RMS

Calculate the root mean square of the linked column entries.

RULE

public static final CalculationOperation RULE

Use an external rule to process the linked column entries.

STD_DEVIATION_OFFSET

public static final CalculationOperation STD_DEVIATION_OFFSET

Calculate the offset from the standard deviation calculation of the linked column. If more than one column is selected, the mean of the row entries is used.

SUM

public static final CalculationOperation SUM

Calculate the sum of the values of the linked column entries.

Method Detail

values

public static CalculationOperation[] 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 (CalculationOperation c : CalculationOperation.values())
    System.out.println(c);

Returns:

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

valueOf

public static CalculationOperation 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

getDisplayName
