Subroutines/Methods

BUILD

Tests to see if the session has expired and if so sets the "authenticated" boolean to false

BUILDARGS

Copies the session values into the hash reference used to instantiate the object from the Plack environment

add_status_message

$message_id = $session->add_status_message( $message );

Appends the message to the message queue for this session. The $message argument is an array reference, first the message then the positional parameters

collect_message_id

$mid = $session->collect_message_id( $req );

Return any pending message id

collect_status_message

$localised_message = $session->collect_status_message( $req );

Returns the next message in the queue (if there is one) for the given request

collect_status_messages

\@localised_messages = $session->collect_status_messages( $req );

Returns previous messages in the queue (if there are any) for the given request or any previous requests

trim_message_queue

$session->trim_message_queue;

Reduce the size of the message queue the maximum allowed by the configuration

update

$session->update;

Copy the attribute values back to the Plack environment
