Syntax

Visual Basic (Usage)Copy Code
Dim instance As NodeState
Dim context As ISystemContext
Dim browsePath As String

instance.GetHierarchyReferences(context, browsePath, hierarchy, references)

Parameters

context
The context for the current operation.
browsePath
The path to the parent object.
hierarchy
A table of all nodes in the hierarchy.
references
The references in the hierarchy.

Remarks

The method is used to serialize any additional references between nodes in the hierarchy. The references are stored as relative paths from the root node. Any references to nodes outside the hierachy are stored as NodeIds instead of relative paths.
