'Declaration
<CLSCompliantAttribute(False)> <NotNullAttribute()> <PureAttribute()> Public Shared Function FromInternalValue( _ ByVal internalValue As Object _ ) As UAPublisherId
'Usage
Dim internalValue As Object Dim value As UAPublisherId value = UAPublisherId.FromInternalValue(internalValue)
[CLSCompliant(false)] [NotNull()] [Pure()] public static UAPublisherId FromInternalValue( object internalValue )
[CLSCompliant(false)] [NotNull()] [Pure()] public: static UAPublisherId^ FromInternalValue( Object^ internalValue )
Parameters
- internalValue
- Internal value of the publisher Id identifier.
The value of this parameter can be
null
(Nothing
in Visual Basic).
Return Value
Because the UASubscribeDataSetFilter has an implicit conversion from UAPublisherId, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned UAPublisherId (containing the publisher Id that you want to allow in the filter) in any place where UASubscribeDataSetFilter is expected as input, and the corresponding OPC UA subscribe dataset filter will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the UASubscribeDataSetFilter.FromUAPublisherId static method instead.
This method never returns null
(Nothing
in Visual Basic).
