C# Class Quickstarts.ViewsServer.ViewsNodeManager

A node manager for a server that exposes several variables.

Inheritance: Opc.Ua.Server.CustomNodeManager2

显示文件 Open project: OPCFoundation/UA-.NET

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.
New ( ISystemContext context, NodeState node ) : Opc.Ua.NodeId	Creates the NodeId for the specified node.
ViewsNodeManager ( IServerInternal server, ApplicationConfiguration configuration ) : System	Initializes the node manager.

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.
IsNodeInView ( ServerSystemContext context, ContinuationPoint continuationPoint, NodeState node ) : bool	Checks if the node is in the view.
IsReferenceInView ( ServerSystemContext context, ContinuationPoint continuationPoint, IReference reference ) : bool	Checks if the reference is in the view.
LoadPredefinedNodes ( ISystemContext context ) : NodeStateCollection	Loads a node set from a file or resource and addes them to the set of predefined nodes.
ValidateNode ( ServerSystemContext context, Opc handle, NodeState>.IDictionary cache ) : NodeState	Verifies that the specified node exists.

Method Details

CreateAddressSpace() public method

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
return	void

DeleteAddressSpace() public method

Frees any resources allocated for the address space.

public DeleteAddressSpace ( ) : void
return	void

Dispose() protected method

An overrideable version of the Dispose.

protected Dispose ( bool disposing ) : void
disposing	bool
return	void

GetManagerHandle() protected method

Returns a unique handle for the node.

protected GetManagerHandle ( ServerSystemContext context, Opc.Ua.NodeId nodeId, NodeState>.IDictionary cache ) : NodeHandle
context	Opc.Ua.Server.ServerSystemContext
nodeId	Opc.Ua.NodeId
cache	NodeState>.IDictionary
return	Opc.Ua.Server.NodeHandle

IsNodeInView() protected method

Checks if the node is in the view.

protected IsNodeInView ( ServerSystemContext context, ContinuationPoint continuationPoint, NodeState node ) : bool
context	Opc.Ua.Server.ServerSystemContext
continuationPoint	Opc.Ua.Server.ContinuationPoint
node	NodeState
return	bool

IsReferenceInView() protected method

Checks if the reference is in the view.

protected IsReferenceInView ( ServerSystemContext context, ContinuationPoint continuationPoint, IReference reference ) : bool
context	Opc.Ua.Server.ServerSystemContext
continuationPoint	Opc.Ua.Server.ContinuationPoint
reference	IReference
return	bool

LoadPredefinedNodes() protected method

Loads a node set from a file or resource and addes them to the set of predefined nodes.

protected LoadPredefinedNodes ( ISystemContext context ) : NodeStateCollection
context	ISystemContext
return	NodeStateCollection

New() public method

Creates the NodeId for the specified node.

public New ( ISystemContext context, NodeState node ) : Opc.Ua.NodeId
context	ISystemContext
node	NodeState
return	Opc.Ua.NodeId

ValidateNode() protected method

Verifies that the specified node exists.

protected ValidateNode ( ServerSystemContext context, Opc handle, NodeState>.IDictionary cache ) : NodeState
context	Opc.Ua.Server.ServerSystemContext
handle	Opc
cache	NodeState>.IDictionary
return	NodeState

ViewsNodeManager() public method

Initializes the node manager.

public ViewsNodeManager ( IServerInternal server, ApplicationConfiguration configuration ) : System
server	IServerInternal
configuration	ApplicationConfiguration
return	System
