| 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.
