## Constructor & Destructor Documentation

## ◆ SimpleStopper()

template<class Iterator >

Xapian::SimpleStopper::SimpleStopper | ( | Iterator | begin,
|  | Iterator | end
| ) |  |
| inline

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.

## Member Function Documentation

## ◆ get_description()

virtual std::string Xapian::SimpleStopper::get_description | ( |  | ) | const
| virtual

Return a string describing this object.

Reimplemented from Xapian::Stopper.

## ◆ operator()()

virtual bool Xapian::SimpleStopper::operator() | ( | const std::string & | term | ) | const
| inlinevirtual

Is term a stop-word?

Parameters

  term | The term to test.

Implements Xapian::Stopper.
