template<class OUTPUT> template<class InputIterator> void DINLINE LStatOutput< OUTPUT >::writeItemsetAndCounter (  InputIterator  first, InputIterator  last, const counter_t  support )  [inline]

Writes out one itemset and its counter. Parameters: first  An input iterator. last  An input iterator. support  the support of the itemset The elements of the itemset are in the range [first, last).
