Members 



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.DataAccess Namespace : UADiscreteItemNode<TValue,TAttribute> Class
The type of the UABaseDataVariable<TValue,TAttribute>.Value of the node.
The type used to access the Value attribute.
This VariableType is an abstract type. I.e., no instances of this type can exist. However, it might be used in a filter when browsing or querying. The DiscreteItemType derives from the DataItemType and therefore shares all of its characteristics.
