Class implementing the UaObject interface for the HistoryServerCapabilitiesType.
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 HistoryServerCapabilitiesType:
Browse Name | TypeDefinition | Modelling Rule | See Also |
---|---|---|---|
AggregateFunctions | FolderType | Mandatory |
Variable members of the HistoryServerCapabilitiesType:
The ServerCapabilitiesType Objects for any OPC UA Server supporting Historical Access shall contain a Reference to a HistoryServerCapabilitiesType Object.
The content of this BaseObjectType is already defined by its type definition in Part 5 of the OPC UA Specification.
The object extensions are intended to inform a Client of the general capabilities of the server. They do not guarantee that all capabilities will be available for all Nodes. For example, not all Nodes will support Events, or in the case of an aggregating server where underlying servers may not support Insert or a particular Aggregate. In such cases, the HistoryServerCapabilities Property would indicate the capability is supported, and the server would return appropriate StatusCodes for situations where the capability does not apply.
All UA servers that support Historical access shall include the HistoryServerCapabilities as part of its ServerCapabilities.
See also HistoryServerCapabilitiesType for a documentation of the complete Information Model.

Construction of the class HistoryServerCapabilitiesType.
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 HistoryServerCapabilitiesType.
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 |
