'Declaration
Public Sub Add( _ ByVal selectClause As UAAttributeField _ )
'Usage
Dim instance As UAEventFilterBuilder Dim selectClause As UAAttributeField instance.Add(selectClause)
public void Add( UAAttributeField selectClause )
public: void Add( UAAttributeField^ selectClause )
Parameters
- selectClause
- Select clause to be added.
Because the UAAttributeField has an implicit conversion from OpcLabs.EasyOpc.UA.Filtering.UASimpleAttributeOperand, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a OpcLabs.EasyOpc.UA.Filtering.UASimpleAttributeOperand in place of this parameter, and the corresponding OPC UA attribute field will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromUASimpleAttributeOperand static method instead.
The value of this parameter cannot be
null
(Nothing
in Visual Basic).
