Enum Constant Detail

INHERIT

public static final SelectionOrder INHERIT

Inherit the value from the parent . If the parent is SHUFFLED, the value is set to ORIGINAL.

This is the default. If there is no such parent, then it defaults to RANDOM.

ORIGINAL

public static final SelectionOrder ORIGINAL

Select in the elements in original order.

RANDOM

public static final SelectionOrder RANDOM

Select in random order, without shuffling the elements. Each element might be selected multiple times.

SHUFFLED

public static final SelectionOrder SHUFFLED

Select in random order by shuffling the elements when a selection iterator is created. Each element will be selected exactly once (if all elements end up being selected). Requires SelectionCacheType.STEP or higher.

Method Detail

values

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

Returns:

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

valueOf

public static SelectionOrder 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

resolve

public static SelectionOrder resolve(SelectionOrder selectionOrder,
                                     SelectionOrder inheritedSelectionOrder)
