Inheritance: IFilterTarget

Public Methods

Method	Description
GetAttributeValue ( FilterContext context, Opc.Ua.NodeId typeDefinitionId, IList relativePath, uint attributeId, NumericRange indexRange ) : object	Returns the value of the attribute for the specified child.
Initialize ( ISystemContext context, BaseInstanceState state ) : void	Initializes the snapshot from an instance.
IsTypeOf ( FilterContext context, Opc.Ua.NodeId typeDefinitionId ) : bool	Returns true if the snapshort is an instance of the specified type.
SetChildValue ( Opc.Ua.QualifiedName browseName, NodeClass nodeClass, object value ) : void	Sets the value for a child. Adds it if it does not already exist.

Method	Description
CreateChildNode ( ISystemContext context, BaseInstanceState state ) : ChildNode	Creates a snapshot of a node.
CreateChildNodes ( ISystemContext context, BaseInstanceState state ) : List	Recusively stores the the current value for Object and Variable child nodes.
GetAttributeValue ( ChildNode node, IList relativePath, int index, uint attributeId ) : object	Returns the value of the attribute for the specified child.
SetChildValue ( ChildNode node, Opc.Ua.QualifiedName browseName, NodeClass nodeClass, object value ) : void	Sets the value for a child. Adds it if it does not already exist.

Returns the value of the attribute for the specified child.
