=head1 NAME

Cache::Object -- the data stored in a Cache.

=head1 DESCRIPTION

Object is used by classes implementing the Cache interface as an
object oriented wrapper around the data.  End users will not normally
use Object directly, but it can be retrieved via the get_object method
on the Cache::Cache interface.

=head1 SYNOPSIS

 use Cache::Object;

 my $object = new Cache::Object( );

 $object->set_key( $key );
 $object->set_data( $data );
 $object->set_expires_at( $expires_at );
 $object->set_created_at( $created_at );


=head1 METHODS

=over

=item B<new(  )>

Construct a new Cache::Object.

=back

=head1 PROPERTIES

=over

=item B<(get|set)_accessed_at>

The time at which the object was last accessed.  Various cache
implementations will use the accessed_at property to store information
for LRU algorithms.  There is no guarentee that all caches will update
this field, however.

=item B<(get|set)_created_at>

The time at which the object was created.

=item B<(get|set)_data>

A scalar containing or a reference pointing to the data to be stored.

=item B<(get|set)_expires_at>

The time at which the object should expire from the cache.

=item B<(get|set)_key>

The key under which the object was stored.

=item B<(get|set)_size>

The size of the frozen version of this object
