Méthodes publiques

Méthode	Description
CreateAddressSpace ( IDictionary externalReferences ) : void	Does any initialization required before the address space can be used. The externalReferences is an out parameter that allows the node manager to link to nodes in other node managers. For example, the 'Objects' node is managed by the CoreNodeManager and should have a reference to the root folder node(s) exposed by this node manager.
DeleteAddressSpace ( ) : void	Frees any resources allocated for the address space.
HistoricalEventsNodeManager ( IServerInternal server, ApplicationConfiguration configuration ) : System	Initializes the node manager.
New ( ISystemContext context, NodeState node ) : Opc.Ua.NodeId	Creates the NodeId for the specified node.

Method Details

CreateAddressSpace() public méthode

Does any initialization required before the address space can be used.

The externalReferences is an out parameter that allows the node manager to link to nodes in other node managers. For example, the 'Objects' node is managed by the CoreNodeManager and should have a reference to the root folder node(s) exposed by this node manager.

public CreateAddressSpace ( IDictionary externalReferences ) : void
externalReferences	IDictionary
Résultat	void

DeleteAddressSpace() public méthode

Frees any resources allocated for the address space.

public DeleteAddressSpace ( ) : void
Résultat	void

Dispose() protected méthode

An overrideable version of the Dispose.

protected Dispose ( bool disposing ) : void
