public final class SubtreeDeleter
extends java.lang.Object

This class provides a utility that can delete all entries below a specified base DN (including the base entry itself by default, although it can be preserved if desired) in an LDAP directory server. It accomplishes this through a combination of search and delete operations. Ideally, it will first perform a search to find all entries below the target base DN, but in some cases, it may be necessary to intertwine search and delete operations if it is not possible to retrieve all entries in the target subtree in advance.

The subtree deleter can optionally take advantage of a number of server features to aid in processing, but does not require them. Some of these features include:

• Set Subtree Accessibility Extended Operation -- A proprietary extended operation supported by the Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 Directory Server products. This operation can restrict access to a specified subtree to all but a specified user. If this is to be used, then the "Who Am I?" extended operation will first be used to identify the user that is authenticated on the provided connection, and then the set subtree accessibility extended operation will be used to make the target subtree hidden and read-only for all users except the user identified by the "Who Am I?" operation. As far as all other clients are concerned, this will make the target subtree immediately disappear. The subtree deleter will then be able to search for the entries to delete, and then delete those entries, without exposing other clients to its in-progress state.
  
  The set subtree accessibility extended operation will not automatically be used. If the setUseSetSubtreeAccessibilityOperationIfAvailable(boolean) method is called with a value of true, then this extended operation will be used if the server root DSE advertises support for both this operation and the LDAP "Who Am I?" extended operation.
  
  
• Simple Paged Results Request Control -- A standard request control that is supported by several types of directory servers. This control allows a search to be broken up into pages to limit the number of entries that are returned in any single operation (which can help an authorized client circumvent search size limit restrictions). It can also help ensure that if the server can return entries faster than the client can consume them, it will not result in a large backlog on the server.
  
  The simple paged results request control will be used by default if the server root DSE advertises support for it, with a default page size of 100 entries.
  
  
• Manage DSA IT Request Control -- A standard request control that is supported by several types of directory servers. This control indicates that any referral entries (that is, entries that contain the "referral" object class and a "ref" attribute) should be treated as regular entries rather than triggering a referral result or a search result reference. The subtree deleter will not make any attempt to follow referrals, and if any referral or search result reference results are returned during processing, then it may not be possible to completely remove all entries in the target subtree.
  
  The manage DSA IT request control will be used by default if the server root DSE advertises support for it.
  
  
• Permit Unindexed Search Request Control -- A proprietary request control supported by the Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 Directory Server products. This control indicates that the client wishes to process the search even if it is unindexed.
  
  The permit unindexed search request control will not automatically be used. It may not needed if the requester has the unindexed-search privilege, and the permit unindexed search request control requires that the caller have either the unindexed-search or unindexed-search-with-control privilege. If the setUsePermitUnindexedSearchControlIfAvailable(boolean) method is called with a value of true, then this control will be used if the server root DSE advertises support for it.
  
  
• LDAP Subentries Request Control -- A standard request control that is supported by several types of directory servers. It allows the client to request a search that retrieves entries with the "ldapSubentry" object class, which are normally excluded from search results. Note that because of the nature of this control, if it is to be used, then two separate sets of searches will be used: one that retrieves only LDAP subentries, and a second that retrieves other types of entries.
  
  The LDAP subentries request control will be used by default if the server root DSE advertises support for it.
  
  
• Return Conflict Entries Request Control -- A proprietary request control that is supported by the Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 Directory Server products. This control indicates that the server should return replication conflict entries, which are normally excluded from search results.
  
  The return conflict entries request control will be used by default if the server root DSE advertises support for it.
  
  
• Soft-Deleted Entry Access Request Control -- A proprietary request control that is supported by the Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 Directory Server products. This control indicates that the server should return soft-deleted entries, which are normally excluded from search results.
  
  The soft-deleted entry access request control will be used by default if the server root DSE advertises support for it.
  
  
• Hard Delete Request Control -- A proprietary request control that is supported by the Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 Directory Server products. This control indicates that the server should process a delete operation as a hard delete, even if a soft-delete policy would have otherwise converted it into a soft delete. A subtree cannot be deleted if it contains soft-deleted entries, so this should be used if the server is configured with such a soft-delete policy.
  
  The hard delete request control will be used by default if the server root DSE advertises support for it.

In servers that support it, this extended operation can make the target subtree hidden and read-only to clients other than those authenticated as the user that issued the set subtree accessibility request.

This method returns true by default. Its value will be ignored if the server root DSE does not indicate that it supports both the set subtree accessibility extended operation and the "Who Am I?" extended operation.

Returns:

true if the set subtree accessibility extended operation should be used to make the target subtree hidden and read-only before attempting to search for entries to delete if the server root DSE advertises support for it, or false if the operation should not be used.

setUseSetSubtreeAccessibilityOperationIfAvailable

public void setUseSetSubtreeAccessibilityOperationIfAvailable(boolean useSetSubtreeAccessibilityOperationIfAvailable)

Specifies whether to use the SetSubtreeAccessibilityExtendedRequest to make the target subtree hidden before starting to search for entries to delete if the server root DSE advertises support for both that extended request and the "Who Am I?" extended request. In servers that support it, this extended operation can make the target subtree hidden and read-only to clients other than those authenticated as the user that issued the set subtree accessibility request.

Parameters:

useSetSubtreeAccessibilityOperationIfAvailable - true to indicate that the set subtree accessibility extended operation should be used to make the target subtree hidden and read-only before starting to search for entries to delete, or false if not.

simplePagedResultsPageSize - The maximum number of entries that should be returned in each page of results when using the simple paged results control. The value must be greater than or equal to one.

useManageDSAITControlIfAvailable

public boolean useManageDSAITControlIfAvailable()

Indicates whether to include the ManageDsaITRequestControl in search and delete requests if the server root DSE advertises support for it. The manage DSA IT request control tells the server that it should return referral entries as regular entries rather than returning them as search result references when processing a search operation, or returning a referral result when attempting a delete. If any referrals are encountered during processing and this control is not used, then it may not be possible to completely delete the entire subtree.

This method returns true by default. Its value will be ignored if the server root DSE does not indicate that it supports the manage DSA IT request control.

Returns:

true if the manage DSA IT request control should be included in search and delete requests if the server root DSE advertises support for it, or false if not.
