dbm::deep::iterator::file::index

DBM::Deep::Iterator::File::Index(3pm)			User Contributed Perl Documentation		     DBM::Deep::Iterator::File::Index(3pm)

NAME

       DBM::Deep::Iterator::Index - mediate between DBM::Deep::Iterator and DBM::Deep::Engine::Sector::Index

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::Index 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 Index 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::Index

   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 an iterator (built by "get_sector_iterator" in DBM::Deep::Iterator) based on the sector pointed to by the next occupied
       location in this index.

       If the sector is exhausted, it returns nothing.
