Constructor & Destructor Documentation
◆ StringValueRangeProcessor() [1/2]

inlineexplicit |
Constructor.
- Parameters
-
slot_ The value number to return from operator().
Definition at line 482 of file queryparser.h.
◆ StringValueRangeProcessor() [2/2]
|
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.

Member Function Documentation
◆ operator()()
|
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.
