詳細描述

This is the Qt OPC UA representation for the OPC UA EUInformation type defined in OPC-UA part 8, 5.6.3. EUInformation values contain information about units and are mostly used as property of a node with a numeric value attribute. The information can e. g. be used to add text and tooltips to GUI elements.
