public interface BackendIndexCfg extends Configuration
Backend Indexes are used to store information that makes it possible to locate entries very quickly when processing search operations.

getAttribute()
Gets the "attribute" property.
|
Integer |
getIndexEntryLimit()
Gets the "index-entry-limit" property.
|
SortedSet<String> |
getIndexExtensibleMatchingRule()
Gets the "index-extensible-matching-rule" property.
|
SortedSet<BackendIndexCfgDefn.IndexType> |
getIndexType()
Gets the "index-type" property.

listener
- The Backend Index configuration change listener.org.forgerock.opendj.ldap.schema.AttributeType getAttribute()
Specifies the name of the attribute for which the index is to be maintained.
Integer getIndexEntryLimit()
Specifies the maximum number of entries that are allowed to match a given index key before that particular index key is no longer maintained.
This is analogous to the ALL IDs threshold in the Sun Java System Directory Server. If this is specified, its value overrides the JE backend-wide configuration. For no limit, use 0 for the value.
SortedSet<String> getIndexExtensibleMatchingRule()
The extensible matching rule in an extensible index.
An extensible matching rule must be specified using either LOCALE or OID of the matching rule.
SortedSet<BackendIndexCfgDefn.IndexType> getIndexType()
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.
int getSubstringLength()
The length of substrings in a substring index.
