UAAttributePointReadParameters Constructor(UAReadParameters)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Connectivity Namespace > UAAttributePointReadParameters Class > UAAttributePointReadParameters Constructor : UAAttributePointReadParameters Constructor(UAReadParameters)
The read parameters to use.

Because the OpcLabs.EasyOpc.UA.UAReadParameters has implicit conversions from System.Double and OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a double precision floating point number (representing the maximum value age in milliseconds), or an OPC UA qualified name (representing the name of the encoding to be used) in place of this parameter, and the corresponding OPC UA read parameters will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromDouble or FromUAQualifiedName static method instead.

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

Creates a new instance of the object, from OpcLabs.EasyOpc.UA.UAReadParameters.
