The following tables list the members exposed by DANodeDescriptor.

Public Constructors

	Name	Description
	DANodeDescriptor Constructor	Overloaded. Initializes a new instance of the DANodeDescriptor class.

Public Fields

	Name	Description
	DefaultItemId	Default Item Id (none, i.e. `null`).
	RootItemId	An Item Id that represents a root of the address space. An empty string.
	RootNodePath	A node path that represents a root of the address space. Equals to `null`. Only used with OPC XML.

Public Properties

	Name	Description
	AliasName	When non-empty, specifies the name of the alias that will be used in place of this object. (Inherited from OpcLabs.EasyOpc.NodeDescriptor)
	ArgumentString	The node descriptor in form of an argument string, i.e. a key=value pairs separated by semicolons. (Inherited from OpcLabs.EasyOpc.NodeDescriptor)
	BrowsePath	Specifies the browse path for the OPC node. (Inherited from OpcLabs.EasyOpc.NodeDescriptor)
	BrowsePathStartingNodeDescriptor	The starting node descriptor of the browse path.
	HasBrowsePath	Determines whether there is a non-null browse path in the descriptor. (Inherited from OpcLabs.EasyOpc.NodeDescriptor)
	HasNodeId	Determines whether there is a non-null node ID in the descriptor. (Inherited from OpcLabs.EasyOpc.NodeDescriptor)
	IsAliased	Determines whether this object is aliased. (Inherited from OpcLabs.EasyOpc.NodeDescriptor)
	IsNull	Determines whether the node descriptor is null, i.e. specifies neither node ID nor a browse path. (Inherited from OpcLabs.EasyOpc.NodeDescriptor)
	IsRoot	Determines whether this object describes a root of the address space. (Inherited from OpcLabs.EasyOpc.NodeDescriptor)
	ItemId	Contains OPC item identifier (empty string for the root, null reference if unknown).
	NodeId	Contains node identifier (empty string for the root, null reference if unknown). (Inherited from OpcLabs.EasyOpc.NodeDescriptor)
	NodePath	Contains node path (empty string for the root, null reference if unknown). Only used with OPC XML. (Inherited from OpcLabs.EasyOpc.NodeDescriptor)
	Null	A null node descriptor (contains a null node ID and a null browse path).
	Root	The node descriptor for the root of the address space.

	GetHashCode	Overridden.
	GetObjectData	(Inherited from OpcLabs.EasyOpc.NodeDescriptor)
	GetSchema	(Inherited from OpcLabs.BaseLib.Info)
	GetType	Gets the System.Type of the current instance. (Inherited from object)
	Match	Determines whether the node descriptor matches another node descriptor. (Inherited from OpcLabs.EasyOpc.NodeDescriptor)
	ReadStringList	(Inherited from OpcLabs.EasyOpc.NodeDescriptor)
	ReadXml	(Inherited from OpcLabs.BaseLib.Info)

Protected Methods

	Name	Description
	DeserializeNodeDescriptorIfPresent	Overridden. Infrastructure.
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from object)
	GetNodeIdArgumentName	Overridden. Infrastructure.
	MakeArgumentString	Infrastructure. (Inherited from OpcLabs.EasyOpc.NodeDescriptor)
	MemberwiseClone	Creates a shallow copy of the current System.Object. (Inherited from object)
