Invoke the read_all on the reader of the Getter port. - c. Invoke the read_all on the reader of the Reader port. -3. Everytime a unexpected sample is received an error message is written. -4.

So the total number of samples on the -Reader port will be : - ((this->iterations_ - 4) * this->keys_ * 2) + - ((this->iterations_ - 13) * this->keys_) - -There'll be also a read action on the Getter port. This'll result in the same amount -of samples as on the Getter port but the samples of the second run will be read -twice and we don't need to decrement the number of keys with one since the Reader -reads also read samples. The following formule determines the number of samples on -the Getter port: - Filtered in during the second run : 3 and 4 (2 samples) - Filtered in during the third run : 22-34 (11 samples) - - ((2 + 2 + 11) * this->keys_); |
