Detailed Description

Class implementing the UaObject interface for the BaseObjectType.

OPC UA Objects are used to represent systems, system components, real-world objects and software objects. They have the NodeClass Object. The detailed description of Objects and their attributes can be found in the general description of the Object node class.

Constructor & Destructor Documentation

OpcUa::BaseObjectType::~BaseObjectType ( ) [protected, virtual]

Destruction of the BaseObjectType. The object is reference counted and can not be deleted directly. The methods addReference and releaseReference are used to manage the reference to this object.

OpcUa::BaseObjectType::BaseObjectType	(	const UaNodeId &	nodeId,
		UaObject *	pInstanceDeclarationObject,
		NodeManagerConfig *	pNodeConfig,
		UaMutexRefCounted *	pSharedMutex = `NULL`
	)

Construction of the class BaseObjectType.

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 NodeId, 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 availablity 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
[in]	pSharedMutex	Shared mutex object used to synchronize access to the object. Can be NULL if no shared mutex is provided

OpcUa::BaseObjectType::BaseObjectType	(	const UaNodeId &	nodeId,
		const UaString &	name,
		OpcUa_UInt16	browseNameNameSpaceIndex,
		NodeManagerConfig *	pNodeConfig,
		UaMutexRefCounted *	pSharedMutex = `NULL`
	)

Construction of the class BaseObjectType.

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 availablity 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
[in]	pSharedMutex	Shared mutex object used to synchronize access to the object. Can be NULL if no shared mutex is provided

UaStatus OpcUa::BaseObjectType::browse	(	const ServiceContext &	serviceContext,
		BrowseContext &	browseContext,
		UaReferenceDescriptions &	References
	)		`[virtual]`

Discover the references of a specified node of a view. This method is used to return a list of references and target nodes for the passed node to browse for the services Browse and BrowseNext.

Returns:: Error code

Parameters:

[in]	serviceContext	General context for the service calls containing information like the session object, return diagnostic mask and timeout hint.
[in]	browseContext	Browse context for the first browse or the following browse with continuation point.
[in]	References	Array of ReferenceDescription results for the browsed node.

Implements UaNode.

UaQualifiedName OpcUa::BaseObjectType::browseName ( ) const [virtual]

Get the browseName of the current Node.

Returns:: the browseName of the current Node.

Implements UaNode.

void OpcUa::BaseObjectType::clearStaticMembers ( ) [static]

Clear the static members of the class

UaLocalizedText OpcUa::BaseObjectType::description ( Session * pSession ) const [virtual]

< [in] Session context for the call.

Get the description as LocalizedText of the current Node.

Returns:: the LocalizedText of the current Node.

Implements UaNode.

UaLocalizedText OpcUa::BaseObjectType::displayName ( Session * pSession ) const [virtual]

< [in] Session context for the call.

Get the displayName as LocalizedText of the current Node.

Returns:: the LocalizedText of the current Node.

Implements UaNode.

OpcUa_Byte OpcUa::BaseObjectType::eventNotifier ( ) const [virtual]

Returns the EventNotifier for the BaseObjectType.

Returns:: the EventNotifier for the BaseObjectType.

Implements UaObject.

MethodManager * OpcUa::BaseObjectType::getMethodManager ( UaMethod * pMethod ) const [virtual]

< [in] Pointer of the Method the MethodManager is requested for.

Returns the method manager interface for the BaseObjectType instance

Reimplemented from UaObject.

UaNode* OpcUa::BaseObjectType::getUaNode ( ) const [inline, virtual]

Get the UaNode interface pointer of this node.

Implements UaReferenceLists.

UaReferenceLists* OpcUa::BaseObjectType::getUaReferenceLists ( ) const [inline, virtual]

Get the UaReferenceLists interface for the node. The UaReferenceLists interface is used to manage and to access the references from and to this node.

Returns:: UaReferenceLists interface for the node.

OpcUa_Boolean OpcUa::BaseObjectType::isDescriptionSupported ( ) const [virtual]

Check if Node is DescriptionSupported.

Returns:: FALSE if not supported.

Implements UaNode.

OpcUa_Boolean OpcUa::BaseObjectType::isUserWriteMaskSupported ( ) const [virtual]

Check if Node is UserWriteMaskSupported.

Returns:: TRUE if Node is UserWriteMaskSupported.

Implements UaNode.

Returns:: TRUE if Node is WriteMaskSupported.

Implements UaNode.

UaNodeId OpcUa::BaseObjectType::modellingRuleId ( ) const [virtual]

Get NodeId of the modelling rule for this node. Only instance declaration nodes like Objects, Variables or Methodss have modelling rulestype definition nodes. This method provides a shortcut to get the modelling rule of a node. This information is available for a client by following the HasModellingRule reference (Browse or TranslateBrowsePathToNodeIds) from this node. The HasModellingRule reference is normally not contained in the list of references for the nodes and is handled by the SDK using this method. Creating the reference as normal reference instead of using this shortcut is also possible. The default implemenation of this method returns a null NodeId which means there is no modelling rule defined. The method must be overwritten in a derived class to return a modelling rule.

Returns:: The modelling rule NodeId for the node if it is an instance declaration node with a modelling rule defined.
