Audio::File::Tag - abstracts the tag of an audio file
Audio::File::Tag is the base class for other file format independant tag classes like Audio::File::Flac::Tag or Audio::File::Ogg::Tag. You shouldn't use this class yourself exept you're writing an own file format dependant subclass.
Constructor. Creates a new Audio::File::Tag object. You shouldn't use this method yourself. It is called by the filetype-dependant subclasses of Audio::File::Type automatically.
Initializes the object. It's called by the constructor and empty by default. It's ought to be overwritten by subclasses.
Using title() you can get or set the tags title field. If called without any argument it'll return the current content of the title field. If you call title() with an scalar argument it will set the title field to what the argument contains. The methods artist(), album(), comment(), genre(), year(), track() and total() are called in the same way.
Set/get the artist field in the files tag.
Set/get the album field in the files tag.
Set/get the comment field in the files tag.
Set/get the genre field in the files tag.
Set/get the year field in the files tag.
Set/get the track field in the files tag.
Set/get the total number of tracks.
Set/get all tags. To set the tags pass a hash reference with the names of the tags as keys and the tag values as hash values. Returns a hash reference if no argument is specified.
Returns whether all tag fields are empty or not.
Saves the changed tag information. Not yet implemented.
