StringValueRangeProcessor() [2/2]

Xapian::StringValueRangeProcessor::StringValueRangeProcessor ( Xapian::valueno slot_, const std::string & str_, bool prefix_ = true )

inline

Constructor.

Parameters

slot_	The value number to return from operator().
str_	A string to look for to recognise values as belonging to this range.
prefix_	Flag specifying whether to check for str_ as a prefix or a suffix.

References prefix, str, and valno.

Member Function Documentation

operator()()

Xapian::valueno Xapian::StringValueRangeProcessor::operator() ( std::string & begin, std::string & end )

virtual

Check for a valid string range.

Parameters

[in,out]	begin	The start of the range as specified in the query string by the user. This parameter is a non-const reference so the ValueRangeProcessor can modify it to return the value to start the range with.
[in,out]	end	The end of the range. This is also a non-const reference so it can be modified.

Returns

A StringValueRangeProcessor always accepts a range it is offered, and returns the value of slot_ passed at construction time. It doesn't modify begin or end.

Implements Xapian::ValueRangeProcessor.
