189 This is a wrapper around a single object in the filemangement.
193 Following methods are wrapper to read the attributes of L<SL::DB::File> :
209 =item C<file_description>
221 Additional are there special methods. If the Object is created by SL::File::get_all_versions()
222 or by "$object->versions"
223 it has a version number. So the different mtime, filepath or content can be retrieved:
229 get the modification time of a (versioned) object
233 get the full qualified file path of the (versioned) object
237 get the content of the (versioned) object
239 =item C<version_count>
241 Get the available versions of the file
245 Returns an array of SL::File::Object objects with the available versions of the file, starting with the newest version.
249 If set this is the newest version of the file.
251 =item C<save_contents $contents>
253 Store a new contents to the file (as a new version).
255 =item C<save_file $filepath>
257 Store the content of an (absolute)file path to the file
261 Delete the file with all of his versions
263 =item C<delete_last_version>
265 Delete only the last version of the file with implicit decrement of the version_count.
269 Delete all old versions of the file. Only one version exist after purge. The version count is reset to 1.
271 =item C<rename $newfilename>
