Detailed Description

An OPCUA Object Node object. This is the "base" of many more complex node. However the defining feature is to create a ObjectNode from a OPCUA TypeDefinition. Example: A ObjectNode can be created with Namespace0NodeId of "FolderType", i.e. the creation for a folder.

Note: OPCUA nodes are available for different node classes (for details refer to:
https://opcfoundation.org/developer-tools/specifications-unified-architecture/part-3-address-space-model/ and
https://opcfoundation.org/developer-tools/specifications-unified-architecture/part-5-information-model/ for details)

Member Function Documentation

◆ CreateFromType()

static ObjectNodePtr CreateFromType	(	const std::uint16_t	NameSpaceIndex,
		const Cvb::String &	Name,
		const OpcUa::NodeID &	Parent,
		const OpcUa::NodeID &	TypeDefinition
	)

inlinestatic

Creates a OPCUA object node with a given type definition.

Note: The nodes will require the node id of the parent node as well as the type definition node id (namspace0 most likely).; Try to avoid using this factory method. Instead use the classes OpcUa::MethodNode or OpcUa::VariableNode (and the derivatives).

Parameters

[in]	NameSpaceIndex	Namespace index for this node. BaseNode will only be visible via the namespace after adding it to a server.
[in]	Name	String literal for non-localized, human-readable name of an OPCUA Node.
[in]	Parent	NodeID of the parent node.
[in]	TypeDefinition	NodeID of the type definition.

Returns: The node

Exceptions

Any	exception derived from std::exception including CvbException and OpcUaException.

Examples: OpcUa/BareboneServer, and OpcUa/ServerClientInteraction.
