DBM::Deep::Iterator::FUser:ContributedDBM::Deep::Iterator::File::BucketList(3)NAME
DBM::Deep::Iterator::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:
· iterator (of type DBM::Deep::Iterator
· 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.
