Inheritance diagram for MetaDataID3V2:

Public Member Functions
void	begin ()
	(re)starts the processing

void	end ()
	Ends the processing and releases the memory.

ID3v2FrameString	frameHeader ()
	provides the current frame header

ID3v2	header ()
	provides the ID3v2 header

bool	isProcessed ()
	returns true if the tag has been provided

void	resize (int size)
	Defines the result buffer size (default is 256);.

void	setCallback (void(fn)(MetaDataType info, const char str, int len))

size_t	write (const uint8_t *data, size_t len)
	provide the (partial) data which might contain the meta data

Protected Member Functions
uint32_t	calcSize (uint8_t chars[4])

bool	encodingIsSupported ()
	For the time beeing we support only ASCII and UTF8.

int	findTag (const char tag, const char str, size_t len)
	find the tag position in the string - if not found we return -1;

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

int	isCharAscii (int ch)

void	processnotifyAudioChange ()
	executes the callbacks

void	processPartialTagAtTail (const uint8_t *data, size_t len)
	We have the beginning of the metadata and need to process the remainder.

void	processTagNotFound (const uint8_t *data, size_t len)
	try to find the metatdata tag in the provided data

int	strpos (char str, const char target)

Protected Attributes
const char *	actual_tag

bool	armed = false

void(*	callback )(MetaDataType info, const char *title, int len)

uint64_t	end_len = 0

ID3v2FrameString	frame_header

Vector< char >	result {0}

int	result_size = 256

ParseStatus	status = TagNotFound

bool	tag_active = false

bool	tag_processed = false

ID3v2	tagv2

uint64_t	total_len = 0

int	use_bytes_of_next_write = 0
