Interface ForumHierarchyDesignSession

All Superinterfaces:

AutoCloseable, Closeable, OsidSession, OsidSession

public interface ForumHierarchyDesignSession
extends OsidSession

This session manages a hierarchy of forums. Forums may be organized into a hierarchy for organizing or federating. A parent Forum includes all of the replies of its children such that a single root node contains all of the replies of the federation.

Like all OsidSessions, ForumHierarchyDesignSessions are dedicated to single processing threads and a single authenticated user.
