Constructor & Destructor Documentation

◆ Source()

ToneGenerator::Source::Source ( const Parameters & params )

Here is the call graph for this function:

◆ ~Source()

ToneGenerator::Source::~Source ( void )

virtual

Destroy a source.

Reimplemented from Media::Source.

Member Function Documentation

◆ canExpandToAllSongs()

virtual bool ToneGenerator::Source::canExpandToAllSongs ( void ) const

overridevirtual

Indicate if arbitrary tracks can be requested from this source.

Returns: True if requests are allowed, false otherwise.

Reimplemented from Media::Source.

◆ createPlaylist() [1/2]

virtual PianodPlaylist* ToneGenerator::Source::createPlaylist	(	const char *	name,
		const Filter &	filter
	)

overridevirtual

Create a playlist using a filter.

Parameters

name	The name of the playlist
filter	The selection criteria.

Returns: The playlist created.

Exceptions

CommandError if a request is invalid.

Reimplemented from Media::Source.

◆ createPlaylist() [2/2]

virtual PianodPlaylist* ToneGenerator::Source::createPlaylist	(	const char *	name,
		MusicThingie::Type	type,
		MusicThingie *	from
	)

overridevirtual

Create a playlist using a thingie as an initial seed.

Seed type allows, for example, to use a song's artist.

Parameters

name	The name of the playlist.
type	The type of seed to create.
from	The initial seed.

Returns: The playlist created.

Exceptions

CommandError if a request is invalid.

Reimplemented from Media::Source.

◆ flush()

virtual bool ToneGenerator::Source::flush ( void )

overridevirtual

Persist data for a source.

Returns: True on success, false on error.

Reimplemented from Media::Source.

◆ getAnythingById()

virtual MusicThingie* ToneGenerator::Source::getAnythingById ( const Media::SplitId & id )

overridevirtual

Implements Media::Source.

◆ getEverythingPlaylist()

virtual PianodPlaylist* ToneGenerator::Source::getEverythingPlaylist ( void )

overridevirtual

Implements Media::Source.

◆ getMixPlaylist()

virtual PianodPlaylist* ToneGenerator::Source::getMixPlaylist ( void )

overridevirtual

Implements Media::Source.

◆ getPlayer()

virtual Media::Player* ToneGenerator::Source::getPlayer	(	const AudioSettings &	audio,
		PianodSong *	song
	)

overridevirtual

Implements Media::Source.

◆ getPlaylists()

virtual PlaylistList ToneGenerator::Source::getPlaylists ( const Filter & filter )

overridevirtual

Retrieve the source's playlists.

Parameters

filter Criteria specifying the subset of the playlists to retrieve.

Returns: Playlists matching the filter, or all playlists if omitted.

Implements Media::Source.

◆ getRandomSongs()

virtual SongList ToneGenerator::Source::getRandomSongs	(	PianodPlaylist *	playlist,
		const UserList &	users,
		Media::SelectionMethod
	)

overridevirtual

Implements Media::Source.

◆ getSuggestion()

virtual MusicThingie* ToneGenerator::Source::getSuggestion	(	MusicThingie *	thing,
		MusicThingie::Type	type,
		SearchRange	where
	)

overridevirtual

Retrieve an equivalent or related album, artist, or song from a source.

To support pianod's engine, this converts items between sources. The engine should not be asking for type conversions within a source.

Parameters

thing	The item to match.
type	The desired type to find.
where	Selects the depth/exhaustiveness of search.

Returns: The single, best-matching item.

Exceptions

CommandError

with:

E_INVALID (inadequate criteria)
E_AMBIGUOUS (multiple matches)
E_NOTFOUND.

Implements Media::Source.

◆ getSuggestions()

virtual ThingieList ToneGenerator::Source::getSuggestions	(	const Filter &	filter,
		SearchRange	where
	)

overridevirtual

Implements Media::Source.

◆ getTransientPlaylist()

virtual PianodPlaylist* ToneGenerator::Source::getTransientPlaylist ( const Filter & criteria )

overridevirtual

Create a temporary playlist based on a filter.

Parameters

criteria A filter specifying the song selection algorithm.

Returns: A temporary playlist, or nullptr if not viable for some reaon.

Exceptions

Reimplemented from Media::Source.

◆ kind()

virtual const char* ToneGenerator::Source::kind ( void ) const

overridevirtual

A unique string identifying the type of source.

Implements Media::Source.

◆ periodic()

virtual float ToneGenerator::Source::periodic ( void )

overridevirtual

Do intermittent or background tasks.

Returns: Suggested time before periodic() be invoked again. No guarantees are offered about actual behavior.

Reimplemented from Media::Source.
