The UnboundID LDAP SDK for Java is a fast, comprehensive, and easy-to-use Java API for communicating with LDAP directory servers and performing related tasks like reading and writing LDIF, encoding and decoding data using base64 and ASN.1 BER, and performing secure communication. This package contains the Standard Edition of the LDAP SDK, which is a complete, general-purpose library for communicating with LDAPv3 directory servers.

/**
 * This class provides an implementation of the LDAP subentries request control
 * as defined in draft-ietf-ldup-subentry.  It may be included in a search
 * request to indicate that the entries with the {@code ldapSubentry} object
 * class should be included in the search results.
 * 


 * Entries containing the {@code ldapSubentry} object class are special in that
 * they are normally excluded from search results, unless the target entry is
 * requested with a base-level search.  They are used to store operational
 * information that controls how the server should behave rather than user data.
 * Because they do not hold user data, it is generally desirable to have them
 * excluded from search results, but for cases in which a client needs to
 * retrieve such an entry, then this subentries request control may be included
 * in the search request.  This control differs from the
 * {@link RFC3672SubentriesRequestControl} in that it will cause only entries
 * with the {@code ldapSubEntry} object class to be returned, while the
 * {@code RFC3672SubentriesRequestControl} may optionally return both regular
 * entries and subentries.
 * 


 * There is no corresponding response control.
 * 


 * Example
 * The following example illustrates the use of the subentries request control
 * to retrieve subentries that may not otherwise be returned.
 *  * // First, perform a search to retrieve an entry with a cn of "test subentry"
 * // but without including the subentries request control.  This should not
 * // return any matching entries.
 * SearchRequest searchRequest = new SearchRequest("dc=example,dc=com",
 *      SearchScope.SUB, Filter.createEqualityFilter("cn", "test subentry"));
 * SearchResult resultWithoutControl = connection.search(searchRequest);
 * LDAPTestUtils.assertResultCodeEquals(resultWithoutControl,
 *      ResultCode.SUCCESS);
 * LDAPTestUtils.assertEntriesReturnedEquals(resultWithoutControl, 0);
 *
 * // Update the search request to add a subentries request control so that
 * // subentries should be included in search results.  This should cause the
 * // subentry to be returned.
 * searchRequest.addControl(new DraftLDUPSubentriesRequestControl());
 * SearchResult resultWithControl = connection.search(searchRequest);
 * LDAPTestUtils.assertResultCodeEquals(resultWithControl, ResultCode.SUCCESS);
 * LDAPTestUtils.assertEntriesReturnedEquals(resultWithControl, 1);
 * 
 *
 * @see  RFC3672SubentriesRequestControl
