NAME
       DBM::Deep::Iterator::BucketList - mediate between DBM::Deep::Iterator and DBM::Deep::Engine::Sector::BucketList

PURPOSE
       This is an internal-use-only object for DBM::Deep. It acts as the mediator between the DBM::Deep::Iterator object and a
       DBM::Deep::Engine::Sector::BucketList sector.

OVERVIEW
       This object, despite the implied class hiearchy, does NOT inherit from DBM::Deep::Iterator. Instead, it delegates to it, essentially acting
       as a facade over it. "get_next_key" in DBM::Deep::Iterator will instantiate one of these objects as needed to handle an BucketList sector.

METHODS
   new(\%params)
       The constructor takes a hashref of params and blesses it into the invoking class. The hashref is assumed to have the following elements:

       o   iterator (of type DBM::Deep::Iterator

       o   sector (of type DBM::Deep::Engine::Sector::BucketList

   at_end()
       This takes no arguments.

       This returns true/false indicating whether this sector has any more elements that can be iterated over.

   get_next_iterator()
       This takes no arguments.

       This returns the next key pointed to by this bucketlist. This value is suitable for returning by FIRSTKEY or NEXTKEY().

       If the bucketlist is exhausted, it returns nothing.
