Exceptions

Exception Description

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. This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

System.ArgumentNullException

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

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks

The getter method of this property is pure, i.e. it does not have observable side effects.

Because the UABrowsePathElementCollection has an implicit conversion from OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedNameCollection, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedNameCollection (containing a sequence of qualified names, assumed to form a relative browse path using "any hierarchical" forward references) in place of UABrowsePathElementCollection value when setting this property, and the corresponding OPC UA browse path element collection will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the UABrowsePathElementCollection.FromUAQualifiedNameCollection static method instead.
