Iterator::File::Source::Interface -- Interface for Iterator::File data sources
All data sources should subclass Iterator::File::Source::Interface & implement the methods defined here.
Iterator::File::Source::Interface inherits from Iterator::File::Utility.
Construct the object. Argument validation. Default assignment.
Any heavy lifting should occur here. E.g., opening a file or shared memory segment.
Advance the iterator & return the new value.
Return the current value, without advancing.
Advance the iterator to $location. If $location is behind the current location, behavior is undefined. (I.e., don't do that.)
Invoked when all is complete so that cleanup may occur.
