UpdateFromPublishedDataSetSourceElement Method



OpcLabs.EasyOpcUAPrimitives Assembly > OpcLabs.EasyOpc.UA.PubSub Namespace > UASubscribeDataSetFilter Class : UpdateFromPublishedDataSetSourceElement Method
The subscribe dataset filter to update. Must not be null.

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 a UAPublisherId (containing the publisher Id that you want to allow in the filter) in place of this parameter, 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 FromUAPublisherId static method instead.

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

The published dataset source element that determines the message type filtering, or null to allow all message types.

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

Updates the subscribe dataset filter based on the published dataset source element type, setting the appropriate message type filters.
