1356 =item C<set_session_value @values>
1358 =item C<set_session_value %values>
1360 Store all values of C<@values> or C<%values> in the session. Each
1361 member of C<@values> is tested if it is a hash reference. If it is
1362 then it must contain the keys C<key> and C<value> and can optionally
1363 contain the key C<auto_restore>. In this case C<value> is associated
1364 with C<key> and restored to C<$::form> upon the next request
1365 automatically if C<auto_restore> is trueish or if C<value> is a scalar
1368 If the current member of C<@values> is not a hash reference then it
1369 will be used as the C<key> and the next entry of C<@values> is used as
1370 the C<value> to store. In this case setting C<auto_restore> is not
1373 Therefore the following two invocations are identical:
1375 $::auth-E<gt>set_session_value(name =E<gt> "Charlie");
1376 $::auth-E<gt>set_session_value({ key =E<gt> "name", value =E<gt> "Charlie" });
1378 All of these values are copied back into C<$::form> for the next
1379 request automatically if they're scalar values or if they have
1380 C<auto_restore> set to trueish.
1382 The values can be any Perl structure. They are stored as YAML dumps.
1384 =item C<get_session_value $key>
1386 Retrieve a value from the session. Returns C<undef> if the value
1389 =item C<create_unique_sesion_value $value, %params>
1391 Create a unique key in the session and store C<$value>
1394 Returns the key created in the session.
1396 =item C<save_session>
1398 Stores the session values in the database. This is the only function
1399 that actually stores stuff in the database. Neither the various
1400 setters nor the deleter access the database.
1402 =item <save_form_in_session %params>
1404 Stores the content of C<$params{form}> (default: C<$::form>) in the
1405 session using L</create_unique_sesion_value>.
1407 If C<$params{non_scalars}> is trueish then non-scalar values will be
1408 stored as well. Default is to only store scalar values.
1410 The following keys will never be saved: C<login>, C<password>,
1411 C<stylesheet>, C<titlebar>, C<version>. Additional keys not to save
1412 can be given as an array ref in C<$params{skip_keys}>.
1414 Returns the unique key under which the form is stored.
1416 =item <restore_form_from_session $key, %params>
1418 Restores the form from the session into C<$params{form}> (default:
1421 If C<$params{clobber}> is falsish then existing values with the same
1422 key in C<$params{form}> will not be overwritten. C<$params{clobber}>
