- - org.forgerock.opendj.server.config.meta.BackendIndexCfgDefn.IndexType

All Implemented Interfaces:

Serializable, Comparable<BackendIndexCfgDefn.IndexType>

Enclosing class:

BackendIndexCfgDefn
```
public static enum BackendIndexCfgDefn.IndexType
extends Enum<BackendIndexCfgDefn.IndexType>
```
Defines the set of permissible values for the "index-type" property.
Specifies the type(s) of indexing that should be performed for the associated attribute.
For equality, presence, and substring index types, the associated attribute type must have a corresponding matching rule.

Enum Constant Summary

Enum Constants
Enum Constant	Description
`APPROXIMATE`	This index type is used to improve the efficiency of searches using approximate matching search filters.
`BIG_EQUALITY`	This index type is used to perform efficient equality filter queries against very high cardinality attribute values.
`BIG_EXTENSIBLE`	This index type is used to improve the efficiency of searches using extensible matching rule search filters against very high cardinality attribute values.
`EQUALITY`	This index type is used to improve the efficiency of searches using equality search filters.
`EXTENSIBLE`	This index type is used to improve the efficiency of searches using extensible matching search filters.
`ORDERING`	This index type is used to improve the efficiency of searches using "greater than or equal to" or "less then or equal to" search filters.
`PRESENCE`	This index type is used to improve the efficiency of searches using the presence search filters.
`SUBSTRING`	This index type is used to improve the efficiency of searches using substring search filters.

- Method Detail
  - values
```
public static BackendIndexCfgDefn.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 (BackendIndexCfgDefn.IndexType c : BackendIndexCfgDefn.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 BackendIndexCfgDefn.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
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Enum<BackendIndexCfgDefn.IndexType>
