Method: new()

Creates a new object of type the Data::Session::ID::AutoIncrement manpage.

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 id_base => $integer

Specifies the base value for the auto-incrementing sessions ids.

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

Note: The first id returned by generate() is id_base + id_step.

The default value is 0.

This key is optional.

o id_file => $file_name

Specifies the file name in which to save the 'current' id.

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

Note: The next id returned by generate() is 'current' id + id_step.

The default value is File::Spec -> catdir(File::Spec -> tmpdir, 'data.session.id').

The reason Data::Session -> new(directory => ...) is not used as the default directory is because this latter option is for where the session files are stored if the driver is File.

This key is optional.

o id_step => $integer

Specifies the amount to be added to the previous id to get the next id.

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

The default value is 1.

This key is optional.

o no_flock => $boolean

Specifies (no_flock => 1) to not use flock() to obtain a lock on $file_name (which holds the 'current' id) before processing it, or (no_flock => 0) to use flock().

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

The default value is 0.

This key is optional.

o umask => $octal_value

Specifies the mode to use when calling sysopen() on $file_name.

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

The default value is 0660.

This key is optional.

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: generate()

Generates the next session id, or dies if it can't.

Returns the new id.

Method: id_length()

Returns 32 because that's the classic value of the size of the id field in the sessions table.

This can be used to generate the SQL to create the sessions table.
