Method Detail

browse

default void browse(ViewManager.BrowseContext context,
                    ViewDescription view,
                    UInteger maxReferencesPerNode,
                    List<BrowseDescription> nodesToBrowse)

browse

CompletableFuture<List<Reference>> browse(AccessContext context,
                                          NodeId nodeId)

If the node identified by nodeId exists return all References.

The AccessContext can be ignored unless the server wishes to impose some restriction upon which users can browse which nodes. Note that this only obscures what is returned in the browse; nothing prevents a client from addressing a NodeId in other service requests, whether they browsed it or not.

Parameters:

context - the AccessContext this request is being made under.

nodeId - the NodeId identifying the node.

Returns:

a CompletableFuture containing the References. If the node is unknown, complete the future exceptionally.
