Class DeleteRequest

  • All Implemented Interfaces:
    ProtocolOp, ReadOnlyDeleteRequest, ReadOnlyLDAPRequest, java.io.Serializable

    @Mutable
    @ThreadSafety(level=NOT_THREADSAFE)
    public final class DeleteRequest
    extends UpdatableLDAPRequest
    implements ReadOnlyDeleteRequest, ProtocolOp
    This class implements the processing necessary to perform an LDAPv3 delete operation, which removes an entry from the directory. A delete request contains the DN of the entry to remove. It may also include a set of controls to send to the server. DeleteRequest objects are mutable and therefore can be altered and re-used for multiple requests. Note, however, that DeleteRequest objects are not threadsafe and therefore a single DeleteRequest object instance should not be used to process multiple requests at the same time.

    Example

    The following example demonstrates the process for performing a delete operation:
     DeleteRequest deleteRequest =
          new DeleteRequest("cn=entry to delete,dc=example,dc=com");
     LDAPResult deleteResult;
     try
     {
       deleteResult = connection.delete(deleteRequest);
       // If we get here, the delete was successful.
     }
     catch (LDAPException le)
     {
       // The delete operation failed.
       deleteResult = le.toLDAPResult();
       ResultCode resultCode = le.getResultCode();
       String errorMessageFromServer = le.getDiagnosticMessage();
     }
