NAME

DBM::Deep::Null - NULL object

PURPOSE

This is an internal-use-only object for DBM::Deep. It acts as a NULL object in the same vein as MARCEL's Class::Null. I couldn't use Class::Null because DBM::Deep needed an object that always evaluated as undef, not an implementation of the Null Class pattern.

OVERVIEW

It is used to represent null sectors in DBM::Deep.
