Creating Hierarchies

IHierarchyContext hierarchyContext = new HierarchyContext();

//hierarchyContext can be set through web appflow layer

hierarchyContext.setUser(user);

hierarchyContext.setSubject(subject);

...

LookupService lookup = LookupServiceFactory.getInstance();

IHierarchyService hierarchyServices = (IHierarchyService)lookup.getModule("hierarchy");

IHierarchyAccessManager haMgr = hierarchyServices.createHierarchyAccessManager(hierarchyContext);

IHierarchy hierarchy =

haMgr.createHierarchy (hierarchyname, hierarchy_type, hierarchyDesc);

.....

Use IHierarchyAccessManager to create a hierarchy, based on the current user or subject information stored in the HierarchyContext. Note that the method acts differently depending on the user role:

• User is a Subscriber. HierarchyAccessException is thrown, because the subscriber is not allowed to create a hierarchy.
• User is a Manager. A new hierarchy is created with a domain ID of the user's company ID, and the user is assigned to the root node of the tree.
• User is a System Administrator. A new hierarchy is created with a domain ID of the user's company id.
