119 A small class that wraps around files that only exist as long as the
120 user's session exists. The session expiration mechanism will delete
121 all session files when the session itself is removed due to expiry or
122 the user logging out.
124 Files are stored in session-specific folders in
125 C<users/session_files/SESSIONID>.
127 =head1 MEMBER FUNCTIONS
131 =item C<new $file_name, [%params]>
133 Create a new instance. C<$file_name> is a relative file name (path
134 components are stripped) to the session-specific temporary directory.
136 If C<$params{mode}> is given then try to open the file as an instance
137 of C<IO::File>. C<${mode}> is passed through to C<IO::File::new>.
139 If C<$params{encoding}> is given then the file is opened with the
140 appropriate encoding layer.
144 Returns the instance of C<IO::File> associated with the file.
148 Returns the full relative file name associated with this instance. If
149 it has been created for "customer.csv" then the value returned might
150 be C<users/session_files/e8789b98721347/customer.csv>.
152 =item C<open, %params]>
154 Opens the file_name given at creation with the given parameters.
158 Returns trueish if the file exists.
162 Returns the file's size in bytes.
164 =item C<displayable_mtime>
166 Returns the modification time suitable for display (e.g. date
167 formatted according to the user's date format), e.g.
168 C<22.01.2011 14:12:22>.
172 =head1 OBJECT FUNCTIONS
178 Returns the name of the session-specific directory used for file
179 storage relative to the kivitendo installation folder.
181 =item C<prepare_path>
183 Creates all directories in C<get_path> if they do not exist. Returns
184 the same as C<get_path>.
186 =item C<destroy_session $id>
188 Removes all files and the directory belonging to the session C<$id>.
