%description
A collection - sometimes called a container - is simply an object that
groups multiple elements into a single unit. _Collection_ are used to
store, retrieve, manipulate, and communicate aggregate data.

The primary advantages of a _Collection_ framework are that it reduces
programming effort by providing useful data structures and algorithms so
you don't have to write them yourself.

The _Collection_ framework consists of:

* * Wrapper Implementations - Add functionality, such as mirroring and lazy
  load, to other implementations.

* * Algorithms - methods that perform useful functions, such as caching.

This module has a task - to be a base class for ather Collections. You can
inherit the methods *_create*, *_delete*, *_fetch*, *_store* and may be
*_prepare_record* for new source of data. As you see this is similar to
*CRUD* (Create - Read - Update- Delete).

Sample:

        my $col = new MyCollection:: <some params>;
        #fetch objects or data by keys
        my $data = $col->fetch(1,2,3,4,5);
        #do something
        foreach my $item ( values %$data) {
            $_->attr->{inc} ++
        }
        #You can use "lazy" functionality
        my $not_actualy_fetch = $col->get_lazy(6,7,8,9);
        #store changed data or objects
        $col->store;
        #free memory
        $col->release;

Sample from the Collection::AutoSQL manpage:

 my $beers = new Collection::AutoSQL::
  dbh     => $dbh,          #database connect
  table   => 'beers',       #table name
  field   => 'bid',         #key field (IDs), usually primary,autoincrement
  cut_key => 1;             #delete field 'bid' from readed records,
    
    my $heineken = $beers->fetch_one(1);
    #SELECT * FROM beers WHERE bid in (1)

Sample from the Collection::Memcached manpage:

    use Collection::Memcached;
    use Cache::Memcached;
    $memd = new Cache::Memcached {
    'servers' => [ "127.0.0.1:11211" ],
    'debug' => 0,
    'compress_threshold' => 10_000,
  };
  my $collection = new Collection::Memcached:: $memd;
  my $collection_prefix = new Collection::Memcached:: $memd, 'prefix';
