Iterator-BreakOn

This module implements break events on an data iterator

It has the following premises:

It works with objects streams.
The source is a reference to an object with a next() method.
This method returns in every call a reference to the next object in the data stream.

It is designed mainly for work with DBIx::Class::ResulSet and similars.

This is a simple usage example:

use Iterator::BreakOn;

my $iter = Iterator::BreakOn->new(

                    datasource => $my_resultset,
                    break_after => [
                        'zipcode' => \&my_dispatch_function
                        ],
                    on_first => \&dispatch_before_first_item,
                    on_last  => \&dispatch_after_last_item,
                    on_every => sub {
                                    ## do something with every item
                                    }
               );

$iter->run();
