Detailed Description

Base class for representing UA Object of any type definition.

The type definition NodeId can be set on instances of this class to represent an OPC UA object of any type.

Constructor & Destructor Documentation

OpcUa::BaseObjectTypeGeneric::~BaseObjectTypeGeneric ( )

protectedvirtual

Destroys the BaseObjectTypeGeneric object.

The destructor is protected since the object is reference counted. It is not possible to delete the object directly.

If the node was added sucessfully to a NodeManager, it can only be deleted by deleting the node from the NodeManager. If the node was not added to a NodeManager or adding the node failed, the node can be deleted by releasing the reference to the node. In addition potential children should be deleted before releasing the reference. The two variations are shown in the following sample code.

BaseObjectTypeGeneric* pObject;
MyNodeManager*  pNodeManager;
// Delete children and release reference if the node was not added to a NodeManager
pObject->deleteAllChildren(pNodeManager);
pObject->releaseReference();
// Delete the node from the NodeManager after it was added to the NodeManager
pNodeManager->deleteUaNode(pObject, OpcUa_True, OpcUa_True, OpcUa_True);

OpcUa::BaseObjectTypeGeneric::BaseObjectTypeGeneric	(	const UaNodeId &	nodeId,
		UaObject *	pInstanceDeclarationObject,
		NodeManagerConfig *	pNodeConfig
	)

Construction of the class BaseObjectTypeGeneric.

This constructor is used if the object is created based on an instance declaration of an object type. Since the only difference between the instance declaration object and the instance object are the node id, the pointer to the instance declaration node is used to get the attribute values other than NodeId from the instance declaration node.
The object is reference counted and can not be deleted directly. The reference counter is set to one after the object is created. If the object was successfully added to a NodeManager using the methods NodeManagerConfig::addUaNode or NodeManagerConfig::addNodeAndReference the NodeManager will release this reference during shut down. If the object was not added to a NodeManager, it must be deleted using the releaseReference method. If the interface pointer is used in other places, the availability of the object must be ensured by incrementing the reference counter with addReference when the pointer is stored somewhere and decremented with releaseReference if the interface pointer is not longer needed.

Parameters

[in]	nodeId	NodeId of the new object
[in]	pInstanceDeclarationObject	UaObject interface of the instance declaration node used to provide attribute values other than NodeId
[in]	pNodeConfig	Interface pointer to the NodeManagerConfig interface used to add and delete node and references in the address space

OpcUa::BaseObjectTypeGeneric::BaseObjectTypeGeneric	(	const UaNodeId &	nodeId,
		const UaString &	name,
		OpcUa_UInt16	browseNameNameSpaceIndex,
		NodeManagerConfig *	pNodeConfig
	)

Construction of the class BaseObjectTypeGeneric.

This constructor is used if the object is not created based on an instance declaration. It defines the name and node id of the object. Additional language specific names and other attribute values can be set with set methods provided by the class. The object is reference counted and can not be deleted directly. The reference counter is set to one after the object is created. If the object was successfully added to a NodeManager using the methods NodeManagerConfig::addUaNode or NodeManagerConfig::addNodeAndReference the NodeManager will release this reference during shut down. If the object was not added to a NodeManager, it must be deleted using the releaseReference method. If the interface pointer is used in other places, the availability of the object must be ensured by incrementing the reference counter with addReference when the pointer is stored somewhere and decremented with releaseReference if the interface pointer is not longer needed.

Parameters

[in]	nodeId	NodeId of the new object
[in]	name	Name of the new object. Used as browse name and also as display name if no additional language specific names are set.
[in]	browseNameNameSpaceIndex	Namespace index used for the browse name
[in]	pNodeConfig	Interface pointer to the NodeManagerConfig interface used to add and delete node and references in the address space

Member Function Documentation

void OpcUa::BaseObjectTypeGeneric::setTypeDefinitionId ( const UaNodeId & typeDefinitionId )

virtual

Sets the type definition NodeId on the instances of this class to represent an OPC UA object of any type.

Parameters

typeDefinitionId Type definition nodeId to use for this object type

UaNodeId OpcUa::BaseObjectTypeGeneric::typeDefinitionId ( ) const

virtual

Get NodeId of the type definition node for this node.

Only Object and Variable nodes have type definition nodes. This method provides a shortcut to get the type definition of a node. This information is available for a client by following the HasTypeDefinition reference (Browse or TranslateBrowsePathToNodeIds) from this node or is returned as part of the browse result for the node. The HasTypeDefinition reference is not contained in the list of references for the nodes and is handled by the SDK using this method.

Returns: The type definition NodeId of the node if the node is a Variable or Object.
