Class RFC3672SubentriesRequestControl

public final class RFC3672SubentriesRequestControl
extends Control
    This class provides an implementation of the LDAP subentries request control as defined in RFC 3672. It may be included in a search request to indicate that entries with the ldapSubEntry object class should be included in the search results. The value of the control indicates whether entries matching the filter but not containing that object class (but ) should also be returned.

    Entries containing the 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 DraftLDUPSubentriesRequestControl in that you can optionally also return entries that do not contain the ldapSubEntry object class, whereas the DraftLDUPSubentriesRequestControl will cause only subentries to be returned.

    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 RFC3672SubentriesRequestControl(true));
 SearchResult resultWithControl = connection.search(searchRequest);
 LDAPTestUtils.assertResultCodeEquals(resultWithControl, ResultCode.SUCCESS);
 LDAPTestUtils.assertEntriesReturnedEquals(resultWithControl, 1);

        Creates a new subentries request control. it will not be marked critical.
        Parameters:
        returnOnlySubEntries - Indicates whether to return only matching entries that contain the ldapSubEntry object class. If this is true, then only subentries will be returned. If this is false, then both both regular entries and subentries may be returned.

      • returnOnlySubEntries

        public boolean returnOnlySubEntries()
        Indicates whether the server should only return matching entries that have the ldapSubEntry object class.
        Returns:
        true if the server should only return matching entries that contain the ldapSubEntry object class, or false if the server may return both regular entries and subentries.
