HashWordCountExample()

auto examples::word_count::HashWordCountExample

(

const DIA< std::string, InputStack > &

input

)

The second WordCount user program: reads a DIA containing std::string words, creates hash values from the words prior to reducing by hash and word. Returns a DIA containing WordCountPairs.

WordCount()

auto examples::word_count::WordCount

(

const DIA< std::string, InputStack > &
