Constructor & Destructor Documentation

◆ SimpleStopper()

template<class Iterator >
Xapian::SimpleStopper::SimpleStopper ( Iterator  begin,
Iterator  end 

Initialise from a pair of iterators.

Xapian includes stopword list files for many languages. You can initialise from a file like so:

std::ifstream words("stopwords/english/stop.txt");
Xapian::SimplerStopper stopper(std::istream_iterator<std::string>(words), std::istream_iterator<std::string>());

In bindings for other languages it isn't possible to pass a C++ iterator pair, so instead this constructor is wrapped to allow passing a filename.
