=head1 NAME
Scrappy::Session - Scrappy Scraper Session Handling
=head1 VERSION
version 0.94112090
=head1 SYNOPSIS
#!/usr/bin/perl
use Scrappy::Session;
my $session = Scrappy::Session->new;
-f 'scraper.sess' ?
$session->load('scraper.sess');
$session->write('scraper.sess');
$session->stash('foo' => 'bar');
$session->stash('abc' => [('a'..'z')]);
=head1 DESCRIPTION
Scrappy::Session provides YAML-Based session file handling for saving recorded
data across multiple execution using the L<Scrappy> framework.
=head2 ATTRIBUTES
The following is a list of object attributes available with every Scrappy::Session
instance.
=head3 auto_save
The auto_save attribute is a boolean that determines whether stash data is
automatically saved to the session file on update.
my $session = Scrappy::Session->new;
$session->load('scraper.sess');
$session->stash('foo' => 'bar');
# turn auto-saving off
$session->auto_save(0);
$session->stash('foo' => 'bar');
$session->write; # explicit write
=head3 file
The file attribute gets/sets the filename of the current session file.
my $session = Scrappy::Session->new;
$session->load('scraper.sess');
$session->write('scraper.sess.bak');
$session->file('scraper.sess');
=head1 METHODS
=head2 load
The load method is used to read-in a session file, it returns its data in the
structure it was saved-in.
my $session = Scrappy::Session->new;
my $data = $session->load('scraper.sess');
=head2 stash
The stash method accesses the stash object which is used to store data to be
written to the session file.
my $session = Scrappy::Session->new;
$session->load('scraper.sess');
$session->stash('foo' => 'bar');
$session->stash('abc' => [('a'..'z')]);
$session->stash->{123} = [(1..9)];
=head2 write
The write method is used to write-out a session file, it saves the data stored
in the session stash and it returns the data written upon completion.
my $session = Scrappy::Session->new;
$session->stash('foo' => 'bar');
$session->stash('abc' => [('a'..'z')]);
$session->stash->{123} = [(1..9)];
my $data = $session->write('scraper.sess');
