Inheritance diagram for AudioDecoder:

Public Member Functions
	AudioDecoder (AudioDecoder const &)=delete

virtual void	addNotifyAudioChange (AudioInfoSupport &bi)
	Adds target to be notified about audio changes.

virtual AudioInfo	audioInfo ()
	provides the actual input AudioInfo

virtual AudioInfo	audioInfoOut ()
	provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream

bool	begin () override

virtual bool	begin (AudioInfo info) override

virtual void	clearNotifyAudioChange ()
	Deletes all change notify subscriptions.

void	end () override

bool	isNotifyActive ()
	Checks if the automatic AudioInfo update is active.

virtual bool	isResultPCM ()
	Returns true to indicate that the decoding result is PCM data.

virtual	operator bool ()=0

AudioDecoder &	operator= (AudioDecoder const &)=delete

virtual bool	removeNotifyAudioChange (AudioInfoSupport &bi)
	Removes a target in order not to be notified about audio changes.

virtual void	setAudioInfo (AudioInfo from) override
	for most decoders this is not needed

void	setNotifyActive (bool flag)
	Deactivate/Reactivate automatic AudioInfo updates: (default is active)

virtual void	setOutput (AudioOutput &out_stream)
	Defines where the decoded result is written to.

virtual void	setOutput (AudioStream &out_stream)
	Defines where the decoded result is written to.

virtual void	setOutput (Print &out_stream) override
	Defines where the decoded result is written to.

virtual size_t	write (const uint8_t *data, size_t len)=0

Public Attributes
int	id
	custom id to be used by application

Protected Member Functions
void	notifyAudioChange (AudioInfo info)

void	writeBlocking (Print out, uint8_t data, size_t len)
