Example 3 with ASN1Integer

use of com.mindbright.asn1.ASN1Integer in project ldapsdk by pingidentity.

the class GetPasswordQualityRequirementsExtendedResult method encodeValue.

/**
 * Encodes the provided information into an ASN.1 octet string suitable for

 *
 * @param  resultCode               The result code for the response.  This
 *                                  must not be {@code null}.
 * @param  passwordRequirements     The password quality requirements for this
 *                                  result.  This must be {@code null} or
 *                                  empty if this result is for an operation
 *                                  that was not processed successfully.  It
 *                                  may be {@code null} or empty if the

 *                                  quality requirements for the target
 *                                  operation.
 * @param  currentPasswordRequired  Indicates whether the user will be
 *                                  required to provide his/her current
 *                                  password when performing a self change.
 *                                  This must be {@code null} if this result
 *                                  is for an operation that was not processed
 *                                  successfully or if the target operation is
 *                                  not a self change.
 * @param  mustChangePassword       Indicates whether the user will be
 *                                  required to change their password after
 *                                  the associated add or administrative
 *                                  reset before that user will be allowed to
 *                                  issue any other requests.  This must be
 *                                  {@code null} if this result is for an
 *                                  operation that was not processed
 *                                  successfully or if the target operation is
 *                                  not an add or an administrative reset.
 * @param  secondsUntilExpiration   Indicates the maximum length of time, in
 *                                  seconds, that the password set in the
 *                                  target operation will be valid.  If
 *                                  {@code mustChangePassword} is {@code true}
 *                                  then this will indicate the length of time
 *                                  that the user has to change his/her
 *                                  password after the add/reset.  If
 *                                  {@code mustChangePassword} is {@code null}
 *                                  or {@code false} then this will indicate
 *                                  the length of time until the password
 *                                  expires.  This must be {@code null} if
 *                                  this result is for an operation that was
 *                                  not processed successfully, or if the new
 *                                  password will be valid indefinitely.
