## Detailed Description

Virtual base class for expand decider functor.

## Member Function Documentation

## operator()()

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

pure virtual

Do we want this term in the ESet?

Parameters

  term | The term to test.

Implemented in Xapian::ExpandDeciderAnd, Xapian::ExpandDeciderFilterTerms, and Xapian::ExpandDeciderFilterPrefix.

## release() [1/2]

ExpandDecider * Xapian::ExpandDecider::release | ( |  | ) |

inline

Start reference counting this object.

You can transfer 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

inline

Start reference counting this object.

You can transfer 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.
