/**
 * 

 *   NOTE:  This class is part of the Commercial Edition of the UnboundID
 *   LDAP SDK for Java.  It is not available for use in applications that
 *   include only the Standard Edition of the LDAP SDK, and is not supported for
 *   use in conjunction with non-UnboundID products.
 * 
 * This class provides an implementation of the password policy state extended
 * request as used in the UnboundID Directory Server.  It may be used to
 * retrieve and/or alter password policy properties for a user account.  See the
 * documentation in the {@link PasswordPolicyStateOperation} class for
 * information about the types of operations that can be performed.
 * 


 * 
Example
 * The following example demonstrates the use of the password policy state
 * extended operation to administratively disable a user's account:
 * 
 * PasswordPolicyStateOperation disableOp =
 *      PasswordPolicyStateOperation.createSetAccountDisabledStateOperation(
 *           true);
 * PasswordPolicyStateExtendedRequest pwpStateRequest =
 *      new PasswordPolicyStateExtendedRequest(
 *               "uid=john.doe,ou=People,dc=example,dc=com", disableOp);
 * PasswordPolicyStateExtendedResult pwpStateResult =
 *      (PasswordPolicyStateExtendedResult)
 *      connection.processExtendedOperation(pwpStateRequest);
 *
 * // NOTE:  The processExtendedOperation method will generally only throw an
 * // exception if a problem occurs while trying to send the request or read
 * // the response.  It will not throw an exception because of a non-success
 * // response.
 *
 * if (pwpStateResult.getResultCode() == ResultCode.SUCCESS)
 * {
 *   boolean isDisabled = pwpStateResult.getBooleanValue(
 *        PasswordPolicyStateOperation.OP_TYPE_GET_ACCOUNT_DISABLED_STATE);
 *   if (isDisabled)
 *   {
 *     // The user account has been disabled.
 *   }
 *   else
 *   {
 *     // The user account is not disabled.
 *   }
 * }
 *
