Detailed Description

Registry for user subclasses.

This class provides a way for the remote server to look up user subclasses when unserialising.

Constructor & Destructor Documentation

Registry() [1/2]

Xapian::Registry::Registry

(

const Registry &

other

)

Copy constructor.

The internals are reference counted, so copying is cheap.

Parameters

other

The object to copy.

Registry() [2/2]

Xapian::Registry::Registry

(

)

Default constructor.

The registry will contain all standard subclasses of user-subclassable classes.

Member Function Documentation

get_lat_long_metric()

const Xapian::LatLongMetric * Xapian::Registry::get_lat_long_metric

(

const std::string &

name

)

const

Get a lat-long metric given a name.

The returned metric is owned by the registry object.

Returns NULL if the metric could not be found.

get_match_spy()

const Xapian::MatchSpy * Xapian::Registry::get_match_spy

(

const std::string &

name

)

const

Get a match spy given a name.

Parameters

name	The name of the match spy to find.

Returns

An object with the requested name, or NULL if the match spy could not be found. The returned object is owned by the registry and so must not be deleted by the caller.

get_posting_source()

const Xapian::PostingSource * Xapian::Registry::get_posting_source

(

const std::string &

name

)

const

Get a posting source given a name.

Parameters

name	The name of the posting source to find.

Returns

An object with the requested name, or NULL if the posting source could not be found. The returned object is owned by the registry and so must not be deleted by the caller.

get_weighting_scheme()

const Xapian::Weight * Xapian::Registry::get_weighting_scheme

(

const std::string &

name

)

const

Get the weighting scheme given a name.

Parameters

name	The name of the weighting scheme to find.

Returns

An object with the requested name, or NULL if the weighting scheme could not be found. The returned object is owned by the registry and so must not be deleted by the caller.

operator=()

Registry & Xapian::Registry::operator=

(

const Registry &

other

)

Assignment operator.

The internals are reference counted, so assignment is cheap.

Parameters

other

The object to copy.

register_match_spy()

void Xapian::Registry::register_match_spy

(

const Xapian::MatchSpy &

spy

)

Register a user-defined match spy class.

Parameters

spy	The match spy to register.

register_posting_source()

void Xapian::Registry::register_posting_source

(

const Xapian::PostingSource &

source

)

Register a user-defined posting source class.

Parameters

source

The posting source to register.

register_weighting_scheme()

void Xapian::Registry::register_weighting_scheme

(

const Xapian::Weight &

wt

)

Register a weighting scheme.

Parameters

wt	The weighting scheme to register.
