virtual int work (int noutput_items, gr_vector_const_void_star &input_items, gr_vector_void_star &output_items)=0
 just like gr::block::general_work, only this arranges to call consume_each for you
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.

Detailed Description

raw stream annotator testing block.

This block creates arbitrary tags to be sent downstream gnuradio/blocks to be sent are set manually via accessor methods and are sent only once.

This block is intended for testing of tag related gnuradio/blocks
