UABrowseParameters Constructor(UANodeClass,UANodeId)

Specifies which reference type will be returned by the browsing.

Because the OpcLabs.EasyOpc.UA.AddressSpace.UANodeId has an implicit conversion from System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (representing the expanded text of the nodeId) in place of this parameter, and the corresponding OPC UA node Id will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.AddressSpace.UANodeId.UANodeId Constructor(String) constructor instead.

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

Initializes a new instance of the class, specifying the node classes, and reference type Id.

'Usage
 
Dim nodeClasses As UANodeClass
Dim referenceTypeId As UANodeId
 
Dim instance As New UABrowseParameters(nodeClasses, referenceTypeId)

public UABrowseParameters(

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

Exceptions

Exception Description

System.ArgumentNullException	A `null` reference (`Nothing` in Visual Basic) is passed to a method that does not accept it as a valid argument.
