Data::Session::Serialize::JSON - A persistent session manager


See Data::Session for details.


Data::Session::Serialize::JSON allows Data::Session to manipulate sessions with JSON.

To use this module do this:

o Specify a driver of type JSON as Data::Session -> new(type => '... serialize:JSON')

Case-sensitive Options

See "Case-sensitive Options" in Data::Session for important information.

Method: new()

Creates a new object of type Data::Session::Serialize::JSON.

new() takes a hash of key/value pairs, some of which might mandatory. Further, some combinations might be mandatory.

The keys are listed here in alphabetical order.

They are lower-case because they are (also) method names, meaning they can be called to set or get the value at any time.

o verbose => $integer

Print to STDERR more or less information.

Typical values are 0, 1 and 2.

This key is normally passed in as Data::Session -> new(verbose => $integer).

This key is optional.

Method: freeze($data)

Returns $data frozen by JSON.

Method: thaw($data)

Returns $data thawed by JSON.
