Enum Constant Detail

DEFAULT

public static final SpaceIndexType DEFAULT

Default value, used for SpaceId. The default is NONE for auto-generated Id, EQUAL otherwise. If the Space ID is compound (multiple properties), a compound index is created.

Since:

16.2

NONE

public static final SpaceIndexType NONE

Not indexed.

BASIC

@Deprecated
public static final SpaceIndexType BASIC

Deprecated. since 12.3 - use EQUAL instead.

Basic index - supports equality.

EXTENDED

@Deprecated
public static final SpaceIndexType EXTENDED

Deprecated. since 12.3 - use ORDERED or EQUAL_AND_ORDERED instead.

Extended(ordered) index - supports comparison.

EQUAL

public static final SpaceIndexType EQUAL

Index that supports equality.

Since:

12.3

ORDERED

public static final SpaceIndexType ORDERED

Index that supports comparison.

Since:

12.3

EQUAL_AND_ORDERED

public static final SpaceIndexType EQUAL_AND_ORDERED

Index that supports both equality and comparison.

Since:

12.3

Method Detail

values

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

Returns:

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

valueOf

public static SpaceIndexType 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

isIndexed

public boolean isIndexed()

Returns:

true if this index type indicates an indexed state, false otherwise.

isOrdered

public boolean isOrdered()
