Public Methods

Method 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.
DsatsDemoNodeManager ( IServerInternal server, ApplicationConfiguration configuration ) : System

Initializes the node manager.
LoadDataSource ( ISystemContext context ) : void

Loads the datasource file.

LoadDataSourceSources ( ISystemContext context, ToolState tool, DsatsDemo datasource, DsatsDemo declaration ) : void
New ( ISystemContext context, NodeState node ) : Opc.Ua.NodeId

Creates the NodeId for the specified node.
OnChangeLockByWrite ( ISystemContext context, NodeState node, NumericRange indexRange, Opc.Ua.QualifiedName dataEncoding, object &value, Opc.Ua.StatusCode &statusCode, System.DateTime &timestamp ) : ServiceResult
OnChangePhase ( ISystemContext context, MethodState method, Opc.Ua.NodeId objectId, Opc.Ua.NodeId phaseId ) : ServiceResult

Handles a request to change the phase.
Read ( OperationContext context, double maxAge, IList nodesToRead, IList values, IList errors ) : void

Reads the value for the specified attribute.

Called when a session is closed.
Write ( OperationContext context, IList nodesToWrite, IList errors ) : void

Writes the value for the specified attributes.

Protected Methods

Method Description
Dispose ( bool disposing ) : void

An overrideable version of the Dispose.
GetManagerHandle ( ServerSystemContext context, Opc.Ua.NodeId nodeId, NodeState>.IDictionary cache ) : NodeHandle

Returns a unique handle for the node.
