For a list of all members of this type, see IEasyUAClientExtension2 members.

Public Methods

	Name	Description
	BrowseTree	Overloaded. Allows to traverse through OPC UA address space nodes under the specified node, using given browse arguments.
	Equals	(Inherited from object)
	GetHashCode	Serves as the default hash function. (Inherited from object)
	GetType	Gets the System.Type of the current instance. (Inherited from object)
	ReadDataType	Overloaded. Reads a value of DataType attribute of a node. If successful, the method returns the actual value of OPC attribute requested. This method also checks whether the returned value is not a `reference`, and is indeed of the OpcLabs.EasyOpc.UA.AddressSpace.UANodeId type. The returned value is therefore always a valid OpcLabs.EasyOpc.UA.AddressSpace.UANodeId.
	ReadDisplayName	Overloaded. Reads a value of DisplayName attribute of a node. If successful, the method returns the actual value of OPC attribute requested. This method also checks whether the returned value is not a `reference`, and is indeed of the System.String type. The returned value is therefore always a valid System.String.
	ReadMultipleDataTypes	Reads value of DataType attribute of multiple nodes, using array of argument objects as an input.
	ReadMultipleDisplayNames	Reads value of DisplayName attribute of multiple nodes, using array of argument objects as an input.
	ReadMultipleNodeClasses	Reads value of NodeClass attribute of multiple nodes, using array of argument objects as an input.
	ReadMultipleNodeIds	Reads value of NodeId attribute of multiple nodes, using array of argument objects as an input.
	ReadNodeClass	Overloaded. Reads a value of NodeClass attribute of a node. If successful, the method returns the actual value of OPC attribute requested. This method also checks whether the returned value is not a `reference`, and is indeed of the OpcLabs.EasyOpc.UA.AddressSpace.UANodeClass type. The returned value is therefore always a valid OpcLabs.EasyOpc.UA.AddressSpace.UANodeClass.
	ReadNodeId	Overloaded. Reads a value of NodeId attribute of a node. If successful, the method returns the actual value of OPC attribute requested. This method also checks whether the returned value is not a `reference`, and is indeed of the OpcLabs.EasyOpc.UA.AddressSpace.UANodeId type. The returned value is therefore always a valid OpcLabs.EasyOpc.UA.AddressSpace.UANodeId.
	RetrieveAllDataTypes	Overloaded. Retrieves all datatype subtypes. The starting node is included as the first element in the result value.
	TestEndpoint	Tests whether an operational connection can be established to the specified endpoint of an OPC UA server.
	ToString	Returns a string that represents the current object. (Inherited from object)
	WaitForMultiple	Overloaded. Waits until the attributes satisfy the given conditions. The WaitForMultiple methods subscribe to the specified nodes&attributes, and monitor their data until the predicates specified for each item become true, or the alloted time elapses.
	WaitForMultipleValues	Overloaded. Waits while the attributes are above the given maximum status severity. The WaitForMultipleValues subscribes to the specified OPC-UA nodes&attributes, and monitor their data until they have at most the status severity specified for each item, an error occurs, or the alloted time elapses.
	WaitForValue	Overloaded. Waits until the specified attribute becomes "good". The WaitForValue methods subscribe to the specified node&attribute, and monitor its data until it has "good" status severity, an error occurs, or the alloted time elapses.

Protected Methods

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

Extension Methods

	Name	Description
	SetState<TNode>	Sets the arbitrary object associated with the node.
