Searching Nodes within a Hierarchy

You can search for hierarchy nodes across all hierarchies to which you have access, within a single hierarchy, or within a sub-tree of a hierarchy. Based on the type of search, you can use methods defined in IHierarchyManger, IHierarchy, or IHierarchyNode to conduct your search.

Code Example: Finding a Root Node for User Within a Hierarchy

IHierarchyNode[] IHierarchy.findRootNodeForUser(IUser)

IHierarchyNode[] IHierarchy.findRootNodeForUser(String uid)

IHierarchyNode[] IHierarchy.findRootNodeForUser2(String userID)

IHierarchyNode[] IHierarchy.findRootNodes2(IUser user) throws DataStoreException

Code Example: Find Node Within a Hierarchy, or a Section of Hierarchy

IHierarchyNode[ ] findNodeByLinkTargetURI(String linkTargetURI)

IHierarchyNode[ ] findNodeByLinkTargetURI(String URI, IPeriod period)

• By Link Target Type

findNodeByLinkTargetType(String linkTargetType)

• By Link Target Id

findNodeByLinkTargetId(string linkTargetId)
