Add Method (UABrowsePath)

The browse element to be appended to the browse path.

Because the UABrowsePathElement has an implicit conversion from OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName (containing a target qualified name, which becomes the "any hierarchical" forward reference) in place of this parameter, and the corresponding OPC UA browse path element will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the UABrowsePathElement.FromUAQualifiedName static method instead.

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

Create a new browse path by appending a browse element to the end of the given browse path.

Syntax

Visual Basic

C++/CLI

'Declaration
 
<NotNullAttribute()>
Public Shared Function Add( _
   ByVal browsePath As UABrowsePath, _
   ByVal element As UABrowsePathElement _
) As UABrowsePath

'Usage
 
Dim browsePath As UABrowsePath
Dim element As UABrowsePathElement
Dim value As UABrowsePath
 
value = UABrowsePath.Add(browsePath, element)

[NotNull()]
public static UABrowsePath Add( 
   UABrowsePath browsePath,
   UABrowsePathElement element
)

[NotNull()]
public:
static UABrowsePath^ Add( 
   UABrowsePath^ browsePath,
   UABrowsePathElement^ element
)

Parameters

browsePath

The browse path.

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

element

The browse element to be appended to the browse path.

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

Return Value

Creates the appended browse path.

Because there is an implicit conversion from UABrowsePath to OpcLabs.EasyOpc.UA.UANodeDescriptor, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned UABrowsePath in any place where the OpcLabs.EasyOpc.UA.UANodeDescriptor is expected as input, and the corresponding node descriptor will be constructed automatically.

This method never returns 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. 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.
