|
|
|
|
|
|
|
|
243
|
|
|
|
|
|
|
L<Audio::MPD::Collection> is a class meant to access & query MPD's |
244
|
|
|
|
|
|
|
collection. You will be able to use those high-level methods instead |
245
|
|
|
|
|
|
|
of using the low-level methods provided by mpd itself. |
246
|
|
|
|
|
|
|
|
247
|
|
|
|
|
|
|
Note that you're not supposed to call the constructor yourself, an |
248
|
|
|
|
|
|
|
L<Audio::MPD::Collection> is automatically created for you during the |
249
|
|
|
|
|
|
|
creation of an L<Audio::MPD> object - it can then be used with the |
250
|
|
|
|
|
|
|
C<collection()> accessor. |
