void | set_taps (const std::vector< float > &taps) |
std::vector< float > | taps () const |
void | set_nthreads (int n) |
Set number of threads to use. | |
int | nthreads () const |
Get number of threads being used. | |
int | work (int noutput_items, gr_vector_const_void_star &input_items, gr_vector_void_star &output_items) |
just like gr_block::general_work, only this arranges to call consume_each for you | |

unsigned | decimation () const |
void | set_decimation (unsigned decimation) |
void | forecast (int noutput_items, gr_vector_int &ninput_items_required) |
Estimate input requirements given output request. | |
int | general_work (int noutput_items, gr_vector_int &ninput_items, gr_vector_const_void_star &input_items, gr_vector_void_star &output_items) |
compute output items from input items | |
int | fixed_rate_ninput_to_noutput (int ninput) |
Given ninput samples, return number of output samples that will be produced. N.B. this is only defined if fixed_rate returns true. Generally speaking, you don't need to override this. | |
int | fixed_rate_noutput_to_ninput (int noutput) |
Given noutput samples, return number of input samples required to produce noutput. N.B. this is only defined if fixed_rate returns true. Generally speaking, you don't need to override this. |
