=head1 NAME
Dancer2::Core::Session - class to represent any session object
=head1 VERSION
version 0.206000_01
=head1 DESCRIPTION
A session object encapsulates anything related to a specific session: its ID,
its data, and its expiration.
It is completely agnostic of how it will be stored, this is the role of
a factory that consumes L<Dancer2::Core::Role::SessionFactory> to know about that.
Generally, session objects should not be created directly.  The correct way to
get a new session object is to call the C<create()> method on a session engine
that implements the SessionFactory role.  This is done automatically by the
app object if a session engine is defined.
=head1 ATTRIBUTES
=head2 id
The identifier of the session object. Required. By default,
L<Dancer2::Core::Role::SessionFactory> sets this to a randomly-generated,
guaranteed-unique string.
This attribute can be modified if your Session implementation requires this.
=head2 data
Contains the data of the session (Hash).
=head2 expires
Number of seconds for the expiry of the session cookie. Don't add the current
timestamp to it, will be done automatically.
Default is no expiry (session cookie will leave for the whole browser's
session).
For a lifetime of one hour:
  expires => 3600
=head2 is_dirty
Boolean value for whether data in the session has been modified.
=head1 METHODS
=head2 read
Reader on the session data
    my $value = $session->read('something');
Returns C<undef> if the key does not exist in the session.
=head2 write
Writer on the session data
  $session->write('something', $value);
Sets C<is_dirty> to true. Returns C<$value>.
=head2 delete
Deletes a key from session data
  $session->delete('something');
Sets C<is_dirty> to true. Returns the value deleted from the session.
