This class implements an enumeration that may be used to define the ways in which an attribute may be indexed within the server.

Enum Constant Summary

Enum Constants

Enum Constant	Description
APPROXIMATE	Used to denote an approximate index, which may be used to identify entries with one or more values that are approximately equal to a specified value.
EQUALITY	Used to denote an equality index, which may be used to identify entries containing a specified value for the associated attribute.
GREATER_OR_EQUAL	Used to denote a greater-or-equal index, which may be used to identify entries with one or more values that are greater than or equal to a specified value.
LESS_OR_EQUAL	Used to denote a less-or-equal index, which may be used to identify entries with one or more values that are less than or equal to a specified value.
PRESENCE	Used to denote a presence index, which may be used to identify entries containing the associated attribute (regardless of the value for that attribute).
SUBANY	Used to denote a subAny index, which may be used to identify entries with one or more values for the associated attribute that contain a specified string.
SUBFINAL	Used to denote a subFinal index, which may be used to identify entries with one or more values for the associated attribute that end with a specified string.
SUBINITIAL	Used to denote a subInitial index, which may be used to identify entries with one or more values for the associated attribute that begin with a specified string.
SUBSTRING	Used to denote a substring index, which may be used to identify entries with one or more values for the associated attribute that match a given substring assertion.

Method Summary

Modifier and Type	Method	Description
static IndexType	forName(String indexName)	Retrieves the index type for the specified name.
String	toString()	Retrieves the human-readable name for this index type.
static IndexType	valueOf(String name)	Returns the enum constant of this type with the specified name.
static IndexType[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

PRESENCE

public static final IndexType PRESENCE

Used to denote a presence index, which may be used to identify entries containing the associated attribute (regardless of the value for that attribute).

EQUALITY

public static final IndexType EQUALITY

Used to denote an equality index, which may be used to identify entries containing a specified value for the associated attribute.

SUBSTRING

public static final IndexType SUBSTRING

Used to denote a substring index, which may be used to identify entries with one or more values for the associated attribute that match a given substring assertion. That substring assertion may contain any or all of subInitial, subAny, and subFinal elements.

SUBINITIAL

public static final IndexType SUBINITIAL

Used to denote a subInitial index, which may be used to identify entries with one or more values for the associated attribute that begin with a specified string.

SUBANY

public static final IndexType SUBANY

Used to denote a subAny index, which may be used to identify entries with one or more values for the associated attribute that contain a specified string.

SUBFINAL

public static final IndexType SUBFINAL

Used to denote a subFinal index, which may be used to identify entries with one or more values for the associated attribute that end with a specified string.

GREATER_OR_EQUAL

public static final IndexType GREATER_OR_EQUAL

Used to denote a greater-or-equal index, which may be used to identify entries with one or more values that are greater than or equal to a specified value.

LESS_OR_EQUAL

public static final IndexType LESS_OR_EQUAL

Used to denote a less-or-equal index, which may be used to identify entries with one or more values that are less than or equal to a specified value.

APPROXIMATE

public static final IndexType APPROXIMATE

Used to denote an approximate index, which may be used to identify entries with one or more values that are approximately equal to a specified value.

Method Detail

values

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

Returns:

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

valueOf

public static IndexType 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

forName

public static IndexType forName(String indexName)

Retrieves the index type for the specified name.

Parameters:

indexName - The name for which to retrieve the associated index type.

Returns:

The requested index type, or null if there is no such index type.

toString

public String toString()

Retrieves the human-readable name for this index type.

Overrides:

toString in class Enum<IndexType>

Returns:

The human-readable name for this index type.
