Class implementing the UaObject interface for the FileType.
The FileType is used to give an OPC UA client access to a file managed by the OPC UA server. After creating a FileType object in the server, the path to the file can be set with FileType::setFilePath
By default the FileType uses the class UaFile for all file access operations. The default behaviour of UaFile can be changed by overwriting FileType::createFileAccessObject. This allows to create a own implementation of UaFile with the application specific behaviour.
The maximum size of the file a client can write to can be limited with FileType::setMaxFileSize. The write access can be set with FileTypeBase::setWritable.
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.

Construction of the class FileType.
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.
[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 |

Construction of the class FileType.
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.
[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::FileType::FileType | ( | UaBase::Object * | pBaseNode, |
XmlUaNodeFactoryManager * | pFactory, | ||
NodeManagerConfig * | pNodeConfig, | ||
UaMutexRefCounted * | pSharedMutex = NULL |
||
) |
Constructs an instance of the class FileType with all components.
[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 |
OpcUa_Boolean OpcUa::FileType::checkUserAccess | ( | Session * | pSession, |
UaIODevice::OpenMode | openMode | ||
) |
Verifies the open mode with the user rights for the file.
The default implementation returns always true. By overwriting this method, the derived class can control access on user level. If the user has not the full rights for the requested openMode, the method returns false.
Creates an object with the interface UaFile used to access the file.
The default implementation creates an instance of UaFile. By overwriting this method, the derived class can create an object that has a specialized implementation of UaFile. The passed in session context can be used to control access on user level.
[in] | pSession | Session context used to access the file. This parameter is only relevant if this method is overwritten by a derived class. |
[in] | sFileName | Name and path of the file to access. |
OpcUa_UInt64 OpcUa::FileType::maxFileSize | ( | ) | const |
Get maximum file size accepted for writing.
Default value 0 is unlimited.
void OpcUa::FileType::setMaxFileSize | ( | OpcUa_UInt64 | maxFileSize | ) |
Set the maximum file size accepted for writing.
Default value 0 is unlimited.
