Method Detail

values

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

Returns:

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

valueOf

public static AbstractWEKAFitnessFunction.Measure valueOf(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:

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

NullPointerException - if the argument is null

adjust

public double adjust(double measure)

Adjusts the measure value for sorting: either multiplies it with -1 or 1.

Parameters:

measure - the raw measure

Returns:

the adjusted measure

isValid

public boolean isValid(weka.core.Instances data)

Checks whether the data can be used with this measure.

Parameters:

data - the data to check

Returns:

true if the measure can be obtain for this kind of data
