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

pure virtual

Do we want this term in the ESet?

ExpandDecider* Xapian::ExpandDecider::release ( )

inline

Start reference counting this object.

You can hand ownership of a dynamically allocated ExpandDecider 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 ExpandDecider* Xapian::ExpandDecider::release ( ) const
