=head2 METHODS

=over

=item C<id>

Returns the ID of the flagtype.

=item C<name>

Returns the name of the flagtype.

=item C<description>

Returns the description of the flagtype.

=item C<cc_list>

Returns the concatenated CC list for the flagtype, as a single string.

=item C<target_type>

Returns whether the flagtype applies to bugs or attachments.

=item C<is_active>

Returns whether the flagtype is active or disabled. Flags being
in a disabled flagtype are not deleted. It only prevents you from
adding new flags to it.

=item C<is_requestable>

Returns whether you can request for the given flagtype
(i.e. whether the '?' flag is available or not).

=item C<is_requesteeble>

Returns whether you can ask someone specifically or not.

=item C<is_multiplicable>

Returns whether you can have more than one flag for the given
flagtype in a given bug/attachment.

=item C<sortkey>

Returns the sortkey of the flagtype.
