Public Methods

Method Description
Add ( IReference reference ) : void

Adds a reference to target entity.
Add ( Opc.Ua.NodeId referenceTypeId, bool isInverse, Opc.Ua.ExpandedNodeId targetId ) : void

Adds a reference to target identified by its node id.
Add ( Opc.Ua.NodeId referenceTypeId, bool isInverse, NodeState target ) : void

Adds a reference to target entity.

Will not add the reference if the browse name does not match the browse name filter.

Dispose ( ) : void

Frees any unmanaged resources.
IsRequired ( Opc.Ua.NodeId referenceType, bool isInverse ) : bool

Returns true if the reference type is required.
IsRequired ( NodeState target ) : bool

Returns true if the target node is required (used to apply view filters);
Next ( ) : IReference

Returns the next reference. Null if no more references.
NodeBrowser ( ISystemContext context, ViewDescription view, Opc.Ua.NodeId referenceType, bool includeSubtypes, BrowseDirection browseDirection, Opc.Ua.QualifiedName browseName, IEnumerable additionalReferences, bool internalOnly ) : System

Creates a new browser object with a set of filters.
Push ( IReference reference ) : void

Pushes a previously returned reference back into the browser.
