ASC

public static final OrderedIndex.OrderDirection ASC

ascending order configuration (default)

DESC

public static final OrderedIndex.OrderDirection DESC

descending order configuration

Method Detail

values

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

Returns:

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

valueOf

public static OrderedIndex.OrderDirection 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

getDirection

public java.lang.String getDirection()

fromString

@Nullable
public static @Nullable OrderedIndex.OrderDirection fromString(@NotNull
                                                               @NotNull java.lang.String direction)

retrieve an OrderDirection from a provided String. Will return null in case of no-match

Parameters:

direction - the direction of the sorting: ascending or descending

Returns:

the direction

fromIndexMeta

public static OrderedIndex.OrderDirection fromIndexMeta(NodeState indexMeta)

tells whether the provided index definition is ascending or descending

Parameters:

indexMeta -

Returns:

the direction

isDescending

public static boolean isDescending(NodeState indexMeta)

convenience method that tells if the provided index definition is descending

Parameters:

indexMeta -

Returns:

true if descending

isAscending

public boolean isAscending()

isDescending

public boolean isDescending()

isAscending

public static boolean isAscending(NodeState indexMeta)

convenience method that tells if the provided index definition is ascending

Parameters:

indexMeta -

Returns:

true if ascending
