ObjectNode Class Reference

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. More...

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.
