@NotMutable @ThreadSafety(level=COMPLETELY_THREADSAFE) public final class SubtreeDeleteRequestControl extends Control
This class provides an implementation of the subtree delete request control as defined in draft-armijo-ldap-treedelete. This can be used to delete an entry and all subordinate entries in a single operation.
Normally, if an entry has one or more subordinates, a directory server will refuse to delete it by rejecting the request with aResultCode.NOT_ALLOWED_ON_NONLEAF
result. In such cases, it is necessary to first recursively remove all of its subordinates before the target entry can be deleted. However, this subtree delete request control can be used to request that the server remove the entry and all subordinates as a single operation. For servers that support this control, it is generally much more efficient and convenient than removing all of the subordinate entries one at a time.
Example
The following example demonstrates the use of the subtree delete control:// First, try to delete an entry that has children, but don't include the // subtree delete control. This delete attempt should fail, and the // "NOT_ALLOWED_ON_NONLEAF" result is most appropriate if the failure reason // is that the entry has subordinates. DeleteRequest deleteRequest = new DeleteRequest("ou=entry with children,dc=example,dc=com"); LDAPResult resultWithoutControl; try { resultWithoutControl = connection.delete(deleteRequest); // We shouldn't get here because the delete should fail. } catch (LDAPException le) { // This is expected because the entry has children. resultWithoutControl = le.toLDAPResult(); ResultCode resultCode = le.getResultCode(); String errorMessageFromServer = le.getDiagnosticMessage(); } LDAPTestUtils.assertResultCodeEquals(resultWithoutControl, ResultCode.NOT_ALLOWED_ON_NONLEAF); // Update the delete request to include the subtree delete request control // and try again. deleteRequest.addControl(new SubtreeDeleteRequestControl()); LDAPResult resultWithControl; try { resultWithControl = connection.delete(deleteRequest); // The delete should no longer be rejected just because the target entry // has children. } catch (LDAPException le) { // The delete still failed for some other reason. resultWithControl = le.toLDAPResult(); ResultCode resultCode = le.getResultCode(); String errorMessageFromServer = le.getDiagnosticMessage(); } LDAPTestUtils.assertResultCodeEquals(resultWithControl, ResultCode.SUCCESS);

SUBTREE_DELETE_REQUEST_OID

SubtreeDeleteRequestControl
public SubtreeDeleteRequestControl()
Creates a new subtree delete request control. The control will not be marked critical.
-
SubtreeDeleteRequestControl
public SubtreeDeleteRequestControl(boolean isCritical)
Creates a new subtree delete request control.- Parameters:
isCritical
- Indicates whether the control should be marked critical.
-
SubtreeDeleteRequestControl
public SubtreeDeleteRequestControl(@NotNull Control control) throws LDAPException
Creates a new subtree delete request control which is decoded from the provided generic control.- Parameters:
control
- The generic control to be decoded as a subtree delete request control.- Throws:
LDAPException
- If the provided control cannot be decoded as a subtree delete request control.
-

Method Detail
-
getControlName
@NotNull public java.lang.String getControlName()
Retrieves the user-friendly name for this control, if available. If no user-friendly name has been defined, then the OID will be returned.- Overrides:
getControlName
in classControl
- Returns:
- The user-friendly name for this control, or the OID if no user-friendly name is available.
-
toJSONControl
@NotNull public JSONObject toJSONControl()
Retrieves a representation of this subtree delete request control as a JSON object. The JSON object uses the following fields (note that since this control does not have a value, neither thevalue-base64
norvalue-json
fields may be present):-
oid
-- A mandatory string field whose value is the object identifier for this control. For the subtree delete request control, the OID is "1.2.840.113556.1.4.805". -
control-name
-- An optional string field whose value is a human-readable name for this control. This field is only intended for descriptive purposes, and when decoding a control, theoid
field should be used to identify the type of control. -
criticality
-- A mandatory Boolean field used to indicate whether this control is considered critical.
- Overrides:
toJSONControl
in classControl
- Returns:
- A JSON object that contains a representation of this control.
-
-
decodeJSONControl
@NotNull public static SubtreeDeleteRequestControl decodeJSONControl(@NotNull JSONObject controlObject, boolean strict) throws LDAPException
Attempts to decode the provided object as a JSON representation of a subtree delete request control.- Parameters:
controlObject
- The JSON object to be decoded. It must not benull
.strict
- Indicates whether to use strict mode when decoding the provided JSON object. If this istrue
, then this method will throw an exception if the provided JSON object contains any unrecognized fields. If this isfalse
, then unrecognized fields will be ignored.- Returns:
- The subtree delete request control that was decoded from the provided JSON object.
- Throws:
LDAPException
- If the provided JSON object cannot be parsed as a valid subtree delete request control.
