Class for the History Variable Handle containing the NodeId for the processing in the HistoryManager.
This class can be used if no other information idenfying the node can be used in the HistoryVariableHandle and the HistoryManager has all node related information to process the history request for the node.

virtual |
Returns the NodeAccessInfo for the Node related to the HistoryVariableHandle Returns Null if the NodeAccessInfo is not available or the derived class does not have acess to the NodeAccessInfo.
The default implementation returns always Null.
Reimplemented from HistoryVariableHandle.
|
virtual |
Returns the extended AccessLevel for the Node related to the HistoryVariableHandle.
The extended AccessLevel is a UInt32 and contains the AccessLevel with data type Byte.
Returns false if the AccessLevel is not available or the derived class does not have acess to the AccessLevel.
The default implementation returns always false.
Reimplemented from HistoryVariableHandle.

Sets the NodeAccessInfo of the Node related to the HistoryVariableHandle Returns a bad status if the NodeAccessInfo cannot be stored in the derived class.
The default implementation returns bad status.
