1286 =item C<set_session_value @values>
1287 =item C<set_session_value %values>
1289 Store all values of C<@values> or C<%values> in the session. Each
1290 member of C<@values> is tested if it is a hash reference. If it is
1291 then it must contain the keys C<key> and C<value> and can optionally
1292 contain the key C<auto_restore>. In this case C<value> is associated
1293 with C<key> and restored to C<$::form> upon the next request
1294 automatically if C<auto_restore> is trueish or if C<value> is a scalar
1297 If the current member of C<@values> is not a hash reference then it
1298 will be used as the C<key> and the next entry of C<@values> is used as
1299 the C<value> to store. In this case setting C<auto_restore> is not
1302 Therefore the following two invocations are identical:
1304 $::auth-E<gt>set_session_value(name =E<gt> "Charlie");
1305 $::auth-E<gt>set_session_value({ key =E<gt> "name", value =E<gt> "Charlie" });
1307 All of these values are copied back into C<$::form> for the next
1308 request automatically if they're scalar values or if they have
1309 C<auto_restore> set to trueish.
1311 The values can be any Perl structure. They are stored as YAML dumps.
1313 =item C<get_session_value $key>
1315 Retrieve a value from the session. Returns C<undef> if the value
1318 =item C<create_unique_sesion_value $value, %params>
1320 Create a unique key in the session and store C<$value>
1323 Returns the key created in the session.
1325 =item C<save_session>
1327 Stores the session values in the database. This is the only function
1328 that actually stores stuff in the database. Neither the various
1329 setters nor the deleter access the database.
1331 =item <save_form_in_session %params>
1333 Stores the content of C<$params{form}> (default: C<$::form>) in the
1334 session using L</create_unique_sesion_value>.
1336 If C<$params{non_scalars}> is trueish then non-scalar values will be
1337 stored as well. Default is to only store scalar values.
1339 The following keys will never be saved: C<login>, C<password>,
1340 C<stylesheet>, C<titlebar>, C<version>. Additional keys not to save
1341 can be given as an array ref in C<$params{skip_keys}>.
1343 Returns the unique key under which the form is stored.
1345 =item <restore_form_from_session $key, %params>
1347 Restores the form from the session into C<$params{form}> (default:
1350 If C<$params{clobber}> is falsish then existing values with the same
1351 key in C<$params{form}> will not be overwritten. C<$params{clobber}>
