Node Id of this node.

Because the 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 UANodeId.UANodeId Constructor(String) constructor instead.

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

The class of the node.
Browse name of the node (this string is intended for programmatic use).

Because the UAQualifiedName 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 qualified name) in place of this parameter, and the corresponding OPC UA qualified name will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the UAQualifiedName.UAQualifiedName Constructor(String) constructor instead.

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

The display name of the node (this string is localized and intended to be human readable).

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

Type Id of the type of this node.

When the implicit conversion operators are not supported (such as with Python.NET), you can use the UANodeId.UANodeId Constructor(String) constructor instead.

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

The node has been reached by following a forward reference.
Initializes a new instance of the class, without a browse path.

Parameters

nodeId
Node Id of this node.

Because the 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 UANodeId.UANodeId Constructor(String) constructor instead.

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

nodeClass
The class of the node.
browseName
Browse name of the node (this string is intended for programmatic use).

Because the UAQualifiedName 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 qualified name) in place of this parameter, and the corresponding OPC UA qualified name will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the UAQualifiedName.UAQualifiedName Constructor(String) constructor instead.

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

displayName
The display name of the node (this string is localized and intended to be human readable).

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

typeDefinition
Type Id of the type of this node.

Because the 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 UANodeId.UANodeId Constructor(String) constructor instead.

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

referenceTypeId
Type Id of the reference that was used to reach the node.

Because the 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 UANodeId.UANodeId Constructor(String) constructor instead.

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

isForward
The node has been reached by following a forward reference.
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.

An invalid enumeration value was used.

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
