Base class for range processors.
| 
 | inlineexplicit | 
Constructor.
| 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 (| in C++): 
 | 
| Xapian::Query Xapian::RangeProcessor::check_range | ( | const std::string & | b, | 
| const std::string & | e | ||
| ) | 
Check prefix/suffix on range.
If they match, remove the prefix/suffix and then call operator()() to try to handle the range.
| 
 | virtual | 
Check for a valid range of this type.
Override this method to implement your own range handling.
| 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). | 
Reimplemented in Xapian::DateRangeProcessor, and Xapian::NumberRangeProcessor.
| 
 | inline | 
Start reference counting this object.
You can transfer ownership of a dynamically allocated RangeProcessor 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.

The value slot to process.
If this range processor isn't value-based, it can ignore this member.
