详细描述

A write operation on an OPC UA server returns a status code which describes if the value could be written and if not, for what reason the write has failed.

In addition to the status code returned by the server, this class also contains the node id, the attribute and the index range from the request to enable a client to match the result with a request.

Objects of this class are returned in the QOpcUaClient::writeNodeAttributesFinished () signal and contain the result of a write operation that was part of a QOpcUaClient::writeNodeAttributes () request.
