UABrowsePath Constructor(UANodeId,UABrowsePathElement[])



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Navigation Namespace > UABrowsePath Class > UABrowsePath Constructor : UABrowsePath Constructor(UANodeId,UABrowsePathElement[])
The starting node descriptor of the browse path.

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).

A sequence of browse path elements that form the path, beginning from the starting node.

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).

The individual elements of the parameter value cannot be null (Nothing in Visual Basic).

Initializes a new browse path from a given array of browse path elements and a starting node Id.

Parameters

startingNodeId
The starting node descriptor of the browse path.

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).

elementArray
A sequence of browse path elements that form the path, beginning from the starting node.

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).

The individual elements of the parameter value cannot be null (Nothing in Visual Basic).

Exceptions
ExceptionDescription

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.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
