Lets see what is inside the gr_adaptive_fir_ccc class
There are two files c++ and header file.
Its declaration can be found in the header gr_adaptive_fir_ccc.h
(http://gnuradio.org/doc/doxygen-3.5/gr__adaptive__fir__ccc_8h_source.html)
The line in header
class GR_CORE_API gr_adaptive_fir_ccc : public gr_sync_decimator
Tells that gr_adaptive_fir_ccc is a publickly derived class of the base class gr_sync_decimator
There are two private variables
(http://plusplussee.blogspot.com/2012/10/difference-between-public-private-and.html)
private:
std::vector d_new_taps; // vector type gr_complex
bool d_updated; // bool
One is of type gr_complex and another is of type bool.
To see the data types in gnuradio please refer to gr_types.h in /usr/local/include/gnuradio
There are two protected variables also
(http://plusplussee.blogspot.com/2012/10/difference-between-public-private-and.html)
protected:
gr_complex d_error; // gr_complex type
std::vector d_taps; // vector type gr_complex
There are two virtual functions
virtual gr_complex error(const gr_complex &out) = 0;
virtual void update_tap(gr_complex &tap, const gr_complex &in) = 0;
whose definition can be overridden to calculate the error signal per output and
to calculate new weight from old, corresponding input respectively.
These two virtual functions are also protected.
There are two public functions
void set_taps(const std::vector &taps);
int work(int noutput_items,
gr_vector_const_void_star &input_items,
gr_vector_void_star &output_items);
for setting the tap weights and calling the work function.
