|
||||
=head1 DESCRIPTION
|
||||
A file in this context is the collection of all versions of a single file saved
|
||||
into the webdav. This module provides methods to access and manipulate these
|
||||
objects.
|
||||
=head1 FUNCTIONS
|
||||
=over 4
|
||||
=item C<versions>
|
||||
Will return all L<SL::Webdav::Object>s found in this file, sorted by version
|
||||
according to the version scheme used.
|
||||
=item C<latest_version>
|
||||
Returns only the latest version object.
|
||||
=item C<load>
|
||||
Loads objects from disk.
|
||||
=item C<store PARAMS>
|
||||
| a32a0746 | Jan Büren | Store a new version on disk. If C<data> is present, it is expected to contain a
|
||
reference to the data to be written in raw encoding.
|
||||
If C<file> is a valid filename then it will be copied.
|
||||
C<file> and C<data> are exclusive.
|
||||
| dc6d8231 | Sven Schöling | |||
If param C<new_version> is set, force a new version, even if the versioning
|
||||
scheme would keep the old one.
