Implementation of the interface NodeManager operating on a generic address space node model.
This class implements most of the functionality necessary for a client to navigate through the nodes of the name space managed by this node manager. A derived class containing the product specific implementation must implement the functions afterStartUp to create the nodes of the address space and beforeShutDown to clean up resources in the node manager. It is possible to add and remove nodes and references by using the interface NodeManagerConfig implemented by this node manager class.

This method is used to get the VariableHandle for a node used to access the related IOManager in the services Read, Write and CreateMonitoredItems. The provided VariableHandle is reference counted. The reference count is 1 after initial creation of the object. The SDK will release its reference after the transaction is finished.

Translates a relative browse path to a node id.
This method is used to request the Server to translate a browse paths to a NodeId for the target node. There could be a list of target nodes but the normal case is a single result for a starting node and a path. The browse path is constructed of a starting Node and a RelativePath. The specified starting Node identifies the Node from which the RelativePath is based. The RelativePath contains a sequence of BrowseNames. The relative path parameter contains a list of relative path elements and the current position of the translate process since the translate can affect more than one node manager and the implementation of this method is only responsible for processing relative path elements and starting nodes managed by the current node manager instance.
serviceContext | General context for the service calls containing information like the session object, return diagnostic mask and timeout hint. |
startingNode | Starting node from where the relative path is defined. |
relativePath | Relative path from the starting node to the searched node including the current position of the translate process. |
