Check for a valid range of this type.
- 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
- If this ValueRangeProcessor recognises the range BEGIN..END it returns the value slot number to range filter on. Otherwise it returns Xapian::BAD_VALUENO.
Implemented in AuthorValueRangeProcessor, TestValueRangeProcessor, Xapian::NumberValueRangeProcessor, Xapian::DateValueRangeProcessor, and Xapian::StringValueRangeProcessor.

Start reference counting this object.
You can hand ownership of a dynamically allocated ValueRangeProcessor 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.
