ToUAQualifiedNameCollection Method (_UABrowsePathElementCollection)

Converts the current relative path to a sequence of qualified names.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<NotNullAttribute()>
Function ToUAQualifiedNameCollection() As UAQualifiedNameCollection

'Usage
 
Dim instance As _UABrowsePathElementCollection
Dim value As UAQualifiedNameCollection
 
value = instance.ToUAQualifiedNameCollection()

[NotNull()]
UAQualifiedNameCollection ToUAQualifiedNameCollection()

[NotNull()]
UAQualifiedNameCollection^ ToUAQualifiedNameCollection();

Return Value

Returns a qualified name collection that contains a sequence of qualified names that form a simple path.

Because the OpcLabs.EasyOpc.UA.Navigation.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 the returned OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedNameCollection (containing a sequence of qualified names, assumed to form a relative browse path using "any hierarchical" forward references) in any place where OpcLabs.EasyOpc.UA.Navigation.UABrowsePathElementCollection is expected as input, 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 FromUAQualifiedNameCollection static method instead.

This method never returns null (Nothing in Visual Basic).

The individual elements of the returned value are never null (Nothing in Visual Basic).

Exception

Description

System.InvalidOperationException

A method call was invalid for the object's current state.

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 browse path element collection must represent a simple relative path. Such path must consist only of elements that specify a forward, any hierarchical reference.

This member or type is for use from COM. It is not meant to be used from .NET or Python. Refer to the corresponding .NET member or type instead, if you are developing in .NET or Python.
