The class template sub_match is used by the regular expression engine to denote sequences of characters matched by marked sub-expressions.
A match is a [begin, end) pair within the target range matched by the regular expression, but with additional observer functions to enhance code clarity.
Only the default constructor is publicly accessible: object of this class are normally constructed and populated as a part of a Template:cpp container during the processing of one of the regex algorithms.
The member functions return defined default values unless the Template:cpp member is true.
