UAAttributeData<TValue> Constructor(TValue,UAStatusCode,DateTime,Int32)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Generic Namespace > UAAttributeData<TValue> Class > UAAttributeData<TValue> Constructor : UAAttributeData<TValue> Constructor(TValue,UAStatusCode,DateTime,Int32)
The typed value of attribute data.

The value of this parameter can be null (Nothing in Visual Basic).

The status code associated with the value.

Because the OpcLabs.EasyOpc.UA.UAStatusCode has implicit conversions from System.Int64 and OpcLabs.EasyOpc.UA.UASeverity, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a long integer (representing the internal status code value), or one of OpcLabs.EasyOpc.UA.UASeverity enumeration members (representing the severity code) in place of this parameter, and the corresponding OPC UA status code will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.UAStatusCode.FromInt64 or OpcLabs.EasyOpc.UA.UAStatusCode.FromUASeverity static method instead.

The value of this parameter cannot be null (Nothing in Visual Basic).

The source timestamp associated with the value.
The number of picoseconds intervals which shall be added to the %%.
Initializes a new instance of the class, with given value, status code and source timestamp.
