Example of use of the class CRecordUserDbGetRoleList (after generating)

You need the microservice ID of the session manager:

public static final IId SESSION_MICROSERVICE_ID = CIdFactory.fromObject("ccf168c1-f18b-4229-85f9-24461a19ee6a");

The own SessionToken is needed to verify the authorization for the change. You need the permission NY_GetListOfRoles.

  private void getRoleList(@NotNull final UUID aToken) throws CException
  {
      final CEnvelope env = CEnvelope.forMicroService(SESSION_MICROSERVICE_ID);

      final CRecord record = CRecordUserDbGetRoleList.create();
      CRecordUserDbGetRoleList.setSessionToken(record,
                                               aToken);
      sendRequest(env,
                  record);
  }

To catch the response of the request, we need a message handler. We add it in the constructor of the message handler registry.

// constructor:
addMessageHandler(CRecordUserDbGetRoleList.ID,
                  this::asyncGetRoleList);

private boolean asyncGetRoleList(@NotNull final CEnvelope aEnvelope,
                                 @NotNull final CRecord aRecord)
{
    if (aEnvelope.isAnswer())
    {
        final int resultCode = aEnvelope.getResultCode();
        if (resultCode == CResultCode.SUCCESS)
        {
            final String[] roles = CRecordUserDbGetRoleList.getRoles(aRecord,
                                                                     null);
            // ...
        }
        return true;
    }
    return false;
}
