An aspect of the invention provides a method for managing information
associated with a hierarchical key. A plurality of hash tables are
created for a plurality of levels of a hierarchy associated with a
hierarchical key, wherein each hash table is associated with a
corresponding level of the hierarchy. Entries are stored within each of
the plurality of hash tables, wherein the entries are associated with key
names that have as many levels as the level associated with the
respective hash table. Furthermore, a reference to a descendant entry
that is in a respective hash table may be stored within each entry.
