Detailed Description

Base class for range processors.

Constructor & Destructor Documentation

Xapian::RangeProcessor::RangeProcessor ( )

inline

Default constructor.

Xapian::RangeProcessor::RangeProcessor	(	Xapian::valueno	slot_,
		const std::string &	str_ = `std::string()`,
		unsigned	flags_ = `0`
	)

inline

Constructor.

Parameters

slot_	Which value slot to generate ranges over.
str_	A string to look for to recognise values as belonging to this range (as a prefix by default, or as a suffix if flags Xapian::RP_SUFFIX is specified).
flags_	Zero or more of the following flags, combined with bitwise-or: Xapian::RP_SUFFIX - require str_ as a suffix instead of a prefix. Xapian::RP_REPEATED - optionally allow str_ on both ends of the range - e.g. $1..$10 or 5m..50m. By default a prefix is only checked for on the start (e.g. date:1/1/1980..31/12/1989), and a suffix only on the end (e.g. 2..12kg).

virtual Xapian::Query Xapian::RangeProcessor::operator()	(	const std::string &	begin,
		const std::string &	end
	)

virtual

Check for a valid range of this type.

Parameters

begin	The start of the range as specified in the query string by the user.
end	The end of the range as specified in the query string by the user (empty string for no upper limit).

Returns: An OP_VALUE_RANGE Query object (or if end.empty(), an OP_VALUE_GE Query object).
