Detailed Description

Class implementing the UaObject interface for the TemporaryFileTransferType.

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.

Object members of the TemporaryFileTransferType:

Browse Name	TypeDefinition	Modelling Rule	See Also
<TransferState>	FileTransferStateMachineType	OptionalPlaceholder

Variable members of the TemporaryFileTransferType:

Browse Name	DataType	TypeDefinition	Modelling Rule	See Also
ClientProcessingTimeout	Duration	PropertyType	Mandatory	getClientProcessingTimeout, setClientProcessingTimeout

Method members of the TemporaryFileTransferType:

Browse Name	Modelling Rule
CloseAndCommit	Mandatory
GenerateFileForRead	Mandatory
GenerateFileForWrite	Mandatory

Defines a type for the representation of temporary file transfers.

The Methods GenerateFileForRead or GenerateFileForWrite generate a temporary FileType Object that is not browsable in the AddressSpace and can only be accessed with the NodeId and FileHandle returned by the Methods in the same Session. This Object is used to transfer the temporary file between OPC UA Client and Server.

The Property ClientProcessingTimeout defines the maximum time in milliseconds the Server accepts between Method calls necessary to complete a file read transfer or a file write transfer transaction. This includes the Method calls to read or write the file content from the virtual temporary FileType Object. If the Client exceeds the timeout between Method calls, the Server may close the file and cancel the corresponding transfer transaction. Any open temporary transfer file shall be deleted if the Session used to create the file is no longer valid.

The TransferState Objects are used to expose the state of a transfer transaction in the case that the preparation of a file for reading or the processing of the file after writing completes asynchronous after the corresponding Method execution. If the transactions are completed when the Method is returned, the optional TransferState Objects are not available. A Server may allow more than one parallel read transfer. A Server may not allow more than one write transfer or a parallel read and writer transfer.

The read file transfer transaction is started with the Method GenerateFileForRead defined by the TemporaryFileTransferType. After a successful call of this Method, the Client reads the file content by calling the Method Read defined by the FileType until the whole file is transferred from the Server to the Client. The transaction is completed by calling the Method Close defined by the FileType.

The write file transfer transaction is started with the Method StartWriteTransfer defined by the TemporaryFileTransferType. After a successful call of this Method, the Client writes the file content by calling the Method Write defined by the FileType until the whole file is transferred from the Client to the Server. The transaction is completed by calling the Method CloseAndCommit defined by the TemporaryFileTransferType. If the Client wants to abort the operation it uses the Close Method of the temporary FileType Object.

Constructor & Destructor Documentation

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

Construction of the class TemporaryFileTransferType.

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

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

Construction of the class TemporaryFileTransferType.

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

OpcUa::TemporaryFileTransferType::TemporaryFileTransferType	(	UaBase::Object *	pBaseNode,
		XmlUaNodeFactoryManager *	pFactory,
		NodeManagerConfig *	pNodeConfig,
		UaMutexRefCounted *	pSharedMutex = `NULL`
	)

Constructs an instance of the class TemporaryFileTransferType with all components.

Parameters

[in]	pBaseNode	The "tree" of nodes that specifies the attributes of the instance and its children
[in]	pFactory	The factory to create the children
[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 variable. Can be NULL if no shared mutex is provided
