Abstract base class for stop-word decision functor.

If you just want to use an existing stopword list, see Xapian::SimpleStopper.

Member Function Documentation

◆ get_description()

virtual std::string Xapian::Stopper::get_description ( ) const

virtual

Return a string describing this object.

Reimplemented in Xapian::SimpleStopper.

◆ operator()()

virtual bool Xapian::Stopper::operator() ( const std::string & term ) const

pure virtual

Is term a stop-word?

Parameters

term	The term to test.

Implemented in Xapian::SimpleStopper.

◆ release() [1/2]

Stopper * Xapian::Stopper::release ( )

inline

Start reference counting this object.

You can transfer ownership of a dynamically allocated Stopper object to Xapian by calling release() and then passing the object to a Xapian method. Xapian will arrange to delete the object once it is no longer required.

◆ release() [2/2]

const Stopper * Xapian::Stopper::release ( ) const
