Inheritance diagram for LSTERExtr:

List of all members.

Public Member Functions
	LSTERExtr (int chunkSize=0)
	Default constructor.
	~LSTERExtr ()
	Destructor.
STEExtr *	setSTEExtractor (STEExtr *extr)
	Set the STE extractor (the previous one is returned)
bool	extract (std::deque< uint16_t > data, int size)
	Run the algorithm and store the results.
float	value (int index=0)
	Retrieve the results (from the index).
int	size ()
	Get the number of available values.
float	min ()
	Lower bound on the outputted values.
float	max ()
	Upper bound on the outputted values.
void	setFloat (string key, float value)
	Set a float parameter (available : "bound", from 0 to 1)
void	setInt (string key, int value)
	Set a int parameter (available : "chunkSize")
float	getFloat (string key)
	Get a float parameter (available : "bound")
int	getInt (string key)
	Get a int parameter (available : "chunkSize")
void	clear ()
	Clear the extractor (forget the previous results)
Public Member Functions inherited from FeatureExtractor
	FeatureExtractor (int chunkSize=0)
	Constructor. Can set the typical chunk size.
virtual	~FeatureExtractor ()
	Virtual destructor : enables each extractor to delete arrays.
bool	extract (std::deque< uint16_t > data, int size, size_t start)
	Idem, but the buffer starts at index start instead (circular buffer)
virtual float	safeValue (int index=0)
	Retrieve the results, with the bounds respected (we apply a min / max)
virtual float	value (int index, float low, float high)
	Retrieve the results, with other bounds.
virtual void	setString (string key, string value)
	Set a string parameter.
virtual string	getString (string key)
	Get a string parameter.
