Inheritance diagram for MetaDataICY:

Public Member Functions
	MetaDataICY (int metaint)
	We just process the Metadata and ignore the audio info.

virtual void	begin () override
	Resets all counters and restarts the prcessing.

virtual void	end () override
	Resets all counters and restarts the prcessing.

virtual bool	hasMetaData ()
	Returns true if the ICY stream contains metadata.

virtual bool	isData ()
	returns true if the actual bytes is an audio data byte (e.g.mp3)

virtual int	metaInt ()
	provides the metaint

virtual void	processChar (char ch)
	character based state engine

virtual void	setAudioDataCallback (void(fn)(const uint8_t str, int len), int bufferLen=1024)
	Defines the audio callback function.

virtual void	setCallback (void(fn)(MetaDataType info, const char str, int len)) override
	Defines the metadata callback function.

virtual void	setIcyMetaInt (int value) override
	Defines the ICE metaint value which is provided by the web call!

virtual Status	status ()
	Returns the actual status of the state engine for the current byte.

virtual size_t	write (const uint8_t *data, size_t len) override
	Writes the data in order to retrieve the metadata and perform the corresponding callbacks.

Protected Member Functions
virtual void	clear ()

virtual bool	isAscii (char *result, int l)
	Make sure that the result is a valid ASCII string.

virtual int	metaSize (uint8_t metaSize)
	determines the meta data size from the size byte

virtual void	processData (char ch)
	Collects the data in a buffer and executes the callback when the buffer is full.

virtual void	processMetaData (char *metaData, int len)
	e.g. StreamTitle=' House Bulldogs - But your love (Radio Edit)';StreamUrl='';

virtual void	setupMetaData (int meta_size)
	allocates the memory to store the metadata / we support changing sizes

Protected Attributes
void(*	callback )(MetaDataType info, const char *str, int len) = nullptr

Status	currentStatus = ProcessData

uint8_t *	dataBuffer =nullptr

void(*	dataCallback )(const uint8_t *str, int len) = nullptr

int	dataLen = 0

int	dataPos = 0

bool	is_data

char *	metaData =nullptr

int	metaDataLen = 0

int	metaDataMaxLen = 0

int	metaDataPos = 0

int	mp3_blocksize = 0

Status	nextStatus = ProcessData

int	totalData = 0
