Public Attributes | |
_BiIter | first |
bool | matched |
_BiIter | second |
A sequence of characters matched by a particular marked sub-expression.
An object of this class is essentially a pair of iterators marking a matched subexpression within a regular expression pattern match. Such objects can be converted to and compared with std::basic_string objects of a similar base character type as the pattern matched by the regular expression.
The iterators that make up the pair are the usual half-open interval referencing the actual original pattern matched.

There is also a templated copy ctor for the pair
class itself.

Two objects may be passed to a pair
constructor to be copied.

Gets the matching sequence as a string.
This is the implicit conversion operator. It is identical to the str() member function except that it will want to pop up in unexpected places and cause a great deal of confusion and cursing from the unwary.
