Example of use of the class CRecordUserDbGetUserList (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");

To fetch the user list, we need the token we received when we logged in. We additionally need the corresponding right to fetch the user list: NY_GetUserList. User rights are stored in the user database by the administrator.

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

    final CRecord record = CRecordUserDbGetUserList.create();
    CRecordUserDbGetUserList.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(CRecordUserDbGetUserList.ID,
                  this::asyncGetUserList);
private boolean asyncGetUserList(@NotNull final CEnvelope aEnvelope,
                                 @NotNull final CRecord aRecord)
{
    if (aEnvelope.isAnswer())
    {
        final int resultCode = aEnvelope.getResultCode();
        if (resultCode == CResultCode.SUCCESS)
        {
            final UUID token = CRecordUserDbGetUserList.getSessionToken(aRecord,
                                                                        null);
            final String[] userIds = CRecordUserDbGetUserList.getUserIds(aRecord,
                                                                         null);
            // ...
        }
        return true;
    }
    return false;
}
