Detailed Description

The manager of the factories for creating instances.

The main use case for this class is to parse a NodeSet XML file using NodeManagerNodeSetXml and to create instances of toolkit classes using the resulting UaBase::BaseNodes.

Constructor & Destructor Documentation

XmlUaNodeFactoryManager::XmlUaNodeFactoryManager ( )

Creates an instance of the XmlUaNodeFactoryManager.

The default XmlUaNodeFactoryNamespace0 for namespace 0 is added by this constructor. It can be overwritten with XmlUaNodeFactoryManager::addNamespace().

Member Function Documentation

void XmlUaNodeFactoryManager::addNamespace	(	XmlUaNodeFactoryNamespace *	pFactoryNamespace,
		bool	deleteAtShutdown = `false`
	)

Adds an additional XmlUaNodeFactoryNamespace to be managed by this instance.

The caller has to delete the XmlUaNodeFactoryNamespace.

OpcUa::BaseMethod * XmlUaNodeFactoryManager::createBaseMethod	(	UaBase::Method *	pMethod,
		UaMutexRefCounted *	pSharedMutex
	)

protectedvirtual

Creates an instance of OpcUa::BaseMethod.

A derived class can overwrite this method to return application specific classes derived from OpcUa::BaseMethod

UaDataType * XmlUaNodeFactoryManager::createDataType	(	UaBase::DataType *	pDataType,
		NodeManagerConfig *	pNodeConfig,
		UaMutexRefCounted *	pSharedMutex = `NULL`
	)

virtual

Creates a DataType node and all properties of the node.

UaMethod * XmlUaNodeFactoryManager::createMethod	(	UaBase::Method *	pMethod,
		NodeManagerConfig *	pNodeConfig,
		UaMutexRefCounted *	pSharedMutex = `NULL`
	)

virtual

Creates a Method with all variables.

Parameters

pMethod	The temporary data representation of the method to create.
pNodeConfig	If pNodeConfig can be casted to NodeManagerNodeSetXml, the callback NodeManagerNodeSetXml::methodCreated is called for each child.
pSharedMutex	An optional mutex that is used across different objects.

UaObject * XmlUaNodeFactoryManager::createObject	(	UaBase::Object *	pObject,
		NodeManagerConfig *	pNodeConfig,
		UaMutexRefCounted *	pSharedMutex = `NULL`
	)

Creates an Object with all components.

The Object is created using the corresponding ObjectType namespace factory. The factory is implemented with XmlUaNodeFactoryNamespace and provided for the namespace with XmlUaNodeFactoryManager::addNamespace().

If you want to influence the Object creation, you need to implement the interface XmlUaNodeFactoryNamespace for the related ObjectType namespace. For the OPC UA namespace you should derive your own implementation from XmlUaNodeFactoryNamespace0 if you want to modify the creation of Objects based on OPCU defined ObjectTypes.

If the namespace of the type definition is not managed by this instance, a generic object with generic children is created.

Parameters

pObject	The temporary data representation of the object to create.
pNodeConfig	The NodeManager to add the children of pObject.
pSharedMutex	An optional mutex that is used across different objects.

UaObjectType * XmlUaNodeFactoryManager::createObjectType	(	UaBase::ObjectType *	pObjectType,
		NodeManagerConfig *	pNodeConfig,
		UaMutexRefCounted *	pSharedMutex = `NULL`
	)

virtual

Creates an ObjectType node including all children.

UaReferenceType * XmlUaNodeFactoryManager::createReferenceType	(	UaBase::ReferenceType *	pReferenceType,
		NodeManagerConfig *	pNodeConfig,
		UaMutexRefCounted *	pSharedMutex = `NULL`
	)

virtual

Creates a ReferenceType node.

void XmlUaNodeFactoryManager::createType ( const UaNodeId & typeId )

virtual

Tries to create a type with a factory.

UaVariable * XmlUaNodeFactoryManager::createVariable	(	UaBase::Variable *	pVariable,
		NodeManagerConfig *	pNodeConfig,
		UaMutexRefCounted *	pSharedMutex = `NULL`
	)

Creates a Variable with all components.

The Variable is created using the corresponding VariableType namespace factory. The factory is implemented with XmlUaNodeFactoryNamespace and provided for the namespace with XmlUaNodeFactoryManager::addNamespace().

If you want to influence the Variable creation, you need to implement the interface XmlUaNodeFactoryNamespace for the related VariableType namespace. For the OPC UA namespace you should derive your own implementation from XmlUaNodeFactoryNamespace0 if you want to modify the creation of Objects based on OPCU defined VariableTypes.

If the namespace of the type definition is not managed by this instance, a generic variable with generic children is created.

Parameters

pVariable	The temporary data representation of the variable to create.
pNodeConfig	The NodeManager to add the children of pVariable.
pSharedMutex	An optional mutex that is used across different variables.

UaVariableType * XmlUaNodeFactoryManager::createVariableType	(	UaBase::VariableType *	pVariableType,
		NodeManagerConfig *	pNodeConfig,
		UaMutexRefCounted *	pSharedMutex = `NULL`
	)

virtual

Creates a VariableType node including all children.

UaVariant XmlUaNodeFactoryManager::defaultValue	(	const UaNodeId &	dataTypeId,
		OpcUa_Int32	valueRank
	)		const

Returns the default value for a DataType with ValueRank valueRank.

If the DataType is unknown, a null value is returned.
